This page will focus on the 14 optional challenge dungeons, followed by final mop-up. While I will write a text guide for each, pointing out where the 8 switches and the Yellow Key are, it is usually quite obvious where to find them. Only a few here and there are tucked away in less-than-obvious spots. Also, while you will see that most of these have two or three Supply Caches, I have only pointed out the ones that are extra during the course of a few dungeons. The first two or three in each dungeon are merely the reward ones at the end for ompleting objectives, and thus should be obvious.
Assuming you have followed along with this guide, you should have 45 Prismatic Cores, meaning your final 35 cores will be obtained here, unlocking Prismatic Perfection. You should also net the achievement for completing all challenge dungeons once, Spelunker. Finally, if you got all the Health Boosters in the story dungeons and overworld, you will unlock Never Felt Better upon grabbing the final one in Tyrant's Forge.
Here is a quick video showing a run of each dungeon, completing all three objectives. The video does not show Health Boosters or Audio Logs, but I have pointed out their locations in the text guides.
If you've followed this guide and have the first four of Bright's audio logs, you will get the last six of them here, one in each of six different dungeons, to unlock Dust Devil.
If you are struggling with cell bots for dungeons, here are links to four of the dungeons' cellbots that are trickier to find, courtesy of site user Purpal Haze.

As you enter the main fighting room, you should see three switches on the far side: Switch #1 (Yellow) down to the left, Switch #2 (Red) directly above the exit door, and Switch #3 (Blue) up high to the right. Standing in the center of the middle platform, look 90 degrees to your left for Switch #4 (Red) above a door with red lights around it. Look left from there to the corner of the room (the right-hand corner when facing back toward the entrance) for Switch #5 (Blue). Once again look left from that switch to see Switch #6 (Yellow) on the same wall as the entrance door, just to the right of it. Continue shifting your gaze left, past the entrance door, to see Switch #7 (Red) in the corner to the left of the entrance.
For the final switch, face the exit. Turn 90 degrees to your right and look at the very top of the room, near a spiky outcropping up and to the right of the red-lighted door in that wall to see Switch #8 (Red). The Yellow Key should be on the right-hand side of the room, out over the green toxic floor. You will probably shoot it down inadvertently during the fight, and it can be difficult to spot if it falls in the toxic green stuff rather than on the rocks right next to the center platform. Even if it’s in the toxic floor, you can jump in to grab it as long as you jump back out quickly. The Health Booster is in the loot room, behind the middle door opened via they yellow key, beside the core container. Look directly underneath the ramp for Audio Log - Bright 07.

Note: Make sure you have the climber bot and flyer bot with you for this one. Look to the left between the first two rolling balls to see Switch #1 (Red). You can shoot it before starting across, or from the platform just past the 2nd ball. Just beyond this, before crossing the red horizontal lasers, look to the right for Switch #2 (Red). To pass the lasers, drop off the platform with the blue arrows on it and wait until you’re lower than the lasers. Dash forward underneath them, then use your double jump to get back up onto the platform beyond. Attach to the metal girder with the climber bot, then onto a 2nd, and finally onto a 3rd to launch over to a stationary platform.
After the next platform you’ll have to go through three blue floating portals. After the third, try to time your landing on the small platform ahead of you so that the twin lasers are moving to your left. Stay on this platform and look to the left of the rolling ball in front of you to see Switch #3 (Red). As it rolls left, dash onto the right-hand end of its platform. Jump and dash over the lasers between this ball and the next, aiming for the left-hand end of the 2nd ball’s platform so that its lasers don’t nail you. Quickly turn so that you’re facing at a 45-degree angle to the right, with straight ahead being the direction you’ve been travelling down this tunnel. Dash off the platform with the ball, double-jump, and dash again to reach a small rock outcropping high up above the next hall.
Directly opposite this outcropping is a ledge with an Audio Log - Bright 06, but ignore that when going for the three challenges at once. Just come back for it and quit out once you grab it. From the small rock outcropping you just landed on, look up to your left to shoot the Yellow Key on a higher ledge nearby and go grab it. This next bit is very tricky. Make sure you have your flyer bot at the ready. You should see two moving platforms with blue bubbles, and some three sets of moving vertical lasers. Between the first and 2nd bubble platforms, a smaller platform moves in and out of a blue force field. Shoot the first bubble platform when the smaller non-bubble one is just starting to come out of the blue force field to the left.
Jump onto the first bubble platform, and onto the smaller one. Now try to wait until the 2nd bubble platform is at the leftmost leg of its path, or as close as possible. Shoot it to drop its bubble and jump over to it. Immediately turn and face back toward the area were the audio log and yellow key were to see Switch #4 (Red), sitting behind that blue force field that the smaller platform was moving through. As soon as you hit it, IMMEDIATELY turn back around and jump along the wall to your left (dash, then double-jump). You’ll have to activate flyer bot with in the middle of this jump to catch the air current from the leftmost pipe, and angle around the lasers possibly (depending on their position), before angling to the right to catch the 2nd air current in order to reach the next platform.
From here, jump over to the 1st small platform to your right, then onto the 2nd one. If you’re quick, and depending on your timing with the double force field moving across these platforms, you can double-jump and dash over the red lasers ahead of you, between the blue force field to the left and the two moving ones to the right. If you’re successful, try to land on the small platform to the left behind the lasers where the Health Booster sits. If your timing is off on that bit, you may have to wait for the double force field to come toward you and jump around it to the next small platform before jumping over the lasers. Once past that bit, move on to the sloped platforms with the rolling balls. Make sure to shoot Switch #5 (Red) on the left, just past this first sloped platform with the rolling ball.
Jump across two more sloped platforms and onto a stationary one with blue arrows. Look ahead to the right of the floating blue portals for Switch #6 (Red) in an alcove. These portals are moving, so remember to time your jumps, hesitating between the 1st and 2nd half of a double jump if necessary, to make it through all three portals. Make sure you don’t wait too long to jump before hitting the 3rd, because if you jump as you pass through it, it negates one of your jump/jump/dash moves, making it hard to reach the small platform beyond. If that happens, you might be able to ‘save’ it by using the flyer bot mid-air. Make your way around the three platforms with rolling balls between the blue force fields, shooting Switch #7 (Red) to the left of the 3rd one, just before the lasers.
From the end of that 3rd platform, drop off so that you pass under the lasers, dash forward, and activate your flyer bot to catch the air current from the pipe ahead. As soon as you land on the platform ahead, switch to climber bot and jump up to the girder moving left to right ahead of you. Attach to it with , pulling back once again on the left stick as you release from the end so that it doesn’t launch you into the lasers. Keep an eye out for the moving platform nearest you beyond the lasers as you drop, and dash toward it as you pass under the lasers, using your double-jump to land on it. Dash/jump over to the next platform and switch to your flyer bot, as this next bit is tricky and might you might need it to rescue you.
Facing forward, you should see a grid of two sets of horizontal lasers with three sets of vertical ones, with moving blue portals. Wait until the nearest portal is moving toward you from the far end of its path before starting your jump. You can shoot Switch #8 (Red) at the far end while you wait. As soon as it starts approaching, dash forward from the platform and double-jump before it reaches you, so that you ‘fall’ through it. Here’s where it gets tricky. If you have the distance, you can then dash/jump or jump/dash forward through the grid into the next portal, but that is unlikely. Most likely, you will want to jump forward to stay as close to the grid as possible, then dash backward the way you came so that you go through the 1st portal again.
This will be a blind dash of sorts, because panning the camera mid-jump would be lunacy. But as long as you use the grid to keep your height roughly centered, you should be fine. Once you pass back through the 1st portal, switch directions again so that you’re moving back toward the grid. You should be able to pass through the 1st portal once more (for a total of three times through it in one continuous jump sequence). From there, you should be close enough to jump through the grid and dash into the next portal. Once you hit that 2nd portal, simply double-jump and dash forward, then use your flyer bot to glide over to the exit.

To your near left as you enter, the Yellow Key is floating up high in the 1st alcove. Make sure you don’t shoot it down above that high ledge, or you can’t reach it. From the entrance, look on the opposite side of the room up high to the left for Switch #1 (Blue), and directly underneath the exit door for Switch #2 (Red). In the upper-right hand corner of the exit door’s wall you’ll find Switch #3 (Red). To the right of that, up high above the alcoves on the right-hand wall, sits Switch #4 (Blue).
Directly to your right as you enter, behind some rocks and a round metal object up against the right-hand wall, Switch #5 (Red) is hiding. Near that one, up high in the right-hand corner nearest you as you enter, you should see Switch #6 (Red). Look directly above the entrance, up high, for Switch #7 (Blue). Lastly, look up into the hole above the large chain in the center for Switch #8 (Blue). The Health Booster is beneath some destructible boxes to your right as you go down the ramp in the loot room.
Brood Hive
4 Core Entry, 2 Prismatic Cores, 10 Supply Caches, 1 Health Booster
From the start, you’ll pass through a short hall and come out onto a ledge. Before dropping down into this room, turn around 180 degrees to find Switch #1(Red) in the starting tunnel. In this first room, look behind you when you drop down to find the Health Booster on a ledge. Switch #2 (Red) is to the right of the exit in this first large fighting room. Switch #3 (Red) is on the right just beyond that exit. Just past #3, look for Supply Cache #1 on your left, and Supply Cache #2 on your right in this hall. Switch #4 (Red) is down the hall from #3, on the left, before turning into the next tunnel on the right, and just before some bat enemies drop down. Look for Switch #5 (Red) at the end of the next hall, up high to your left in a tall vertical shaft.
Climb up that shaft to the top to find Supply Cache #3. Drop down and head into the next room with the three floating platforms. In this room, you’ll need to jump down to the lower area and extract a core from the wall on the far side to bring the moving platforms down. After that, you need to jump back up to the platform where you entered, using the nearest moving one to do so (shoot its bubble to make it usable). Once up there again, press the green pressure plate and jump across the three moving platforms to reach the exit. Before you press that switch, there are some items to grab. Look to your left 90 degrees when facing the exit at the first switch. You should see a climber bot girder on the wall. Use it to reach that alcove for Supply Cache #4.
Look directly underneath the platform with the green pressure plat for Supply Cache #5. Return to the pressure plate and face the exit again. Look for a platform on the right side of the room when facing the exit. Jump over to it, using the floating ones if necessary (shoot the bubble to drop it). Stand on the green switch on the stationary platform, and look diagonally across the room to the doorway the switch opens (to the left of the exit). Shoot the two floating platforms to your right to make a path, then jump and dash your way across them quickly to that doorway before it closes. In this room, you’ll find the Yellow Key a short distance ahead to your left, and Switch #6 (Red) below the ledge to your right as you enter.
Supply Cache #6 is immediately to your left as you enter. This is the only one outside the loot room that has a blueprint. Supply Cache #7 is on the far side of the room behind the door that the green pressure plate opens. The final three caches are in the loot room. Return to the previous room with the three floating platforms once more. This time, stand on the pressure plat on the entrance platform and use the three moving ones, shooting them to freeze them once more, to reach the exit. You should see Switch #7 (Red) to your right shortly after entering this hall. When you enter the final large fighting room, look down behind the rocks to your immediate left as you enter (to the right if you’re facing the door from which you entered while down on the ground), to find Switch #8 (Red).
Cavern Rush

Switch #1 is to your right as you cross the first set of stationary platforms, around the 8th platform. Just after you cross the first two moving platforms, Switch #2 is to the left. At the end of the first platform path, the Yellow Key is above the island, and Switch #3 is on the island. Switch #4 is to the right just ahead of the 6th platform past the island, beside a climber bot girder (which saves you time if you have the climber bot).
Just past this, there is one stationary platform with two moving platforms ahead of it, with very large gaps. Switch #5 is above these, to the left, and the Health Booster is to the left as well, where the 2nd of the moving platforms goes. Look low and to your right as you pass the 3rd blue force field on the next path for Switch #6, with Switch #7 being shortly ahead of this and to the left. Switch #8 is just below the exit, hard to miss.
Coliseum

From the entrance to the main fighting room, look directly across to the exit and underneath it for Switch #1 (Red). The Yellow Key should be floating around between the center platform and the outer walls, so it will drop down into the lava when you shoot it. It should be near the exit as you enter the room. Just jump out and grab it, quickly jumping back before sinking into the lava. To the right of the exit, way up high near the ceiling, Switch #2 (Blue) is visible. Right of that and down lower (almost at your level), Switch #3 (Yellow) sits about midway up the wall on the right side of the room when facing the exit, just left of a white structure.
Continue panning right from that, past the white structure, and up high for Switch #4 (Red), to the left of the exit when facing it. You should be facing back toward the exit now, so look directly above it for Switch #5 (Blue), and to the right of that in the corner for Switch #6 (Red). Standing in the center of the room and facing the exit, look left above a lava flow for Switch #7 (Blue). Finally, face the exit from the center of the platform. Move to the right-side corner nearest the exit and look down over the ledge for Switch #8 (Yellow). You can’t miss the Health Booster, as it is right at the bottom of the ramp in the loot room. Audio Log - Bright 08 is just beside the ramp here.
Crucible
8 Core Entry, 2 Prismatic Cores, 3 Supply Caches, 1 Health Booster
You can hit the switches here more or less in any order, since it’s just a fighting pit. I’ll number them in the order of my video, but you may hit one or more by sheer accident while fighting. Switch #1 (Blue) is to the immediate right of the exit door, near ground level. When facing the exit door, to the right of Switch #1 and up higher, Switch #2 (red) is floating up higher, partially hidden by the round wreckage on the rock wall. Switch #3 (Blue) is between the first two, very high up on the rock wall. The Yellow Key is floating to the left of the exit door, between the grey rock outcroppings. Near this, you’ll find Switch #4 (Yellow) on ground level, hiding behind the rock outcroppings on the left when facing the exit door.
Standing in the center of the room and facing the exit, look directly to your left to see Switch #5 (Red) sitting atop an angled rock pillar, with Switch #6 (Red) just above and to the left of it, atop another pillar. Standing in the center of the room, face the entrance. Switch #7 (Blue) should be just to the right of the entrance, easy to spot. Look to the left of the entrance when facing it from the center of the room, way up high for Switch #8 (Yellow). Now, just finish off all the enemies within the time limit to nail all three challenges on this one. The Health Booster is hard to miss, directly behind the core container at the base of the ramp in the loot room.
Forsaken Halls
16 Core Entry, 3 Prismatic Cores, 2 Supply Caches, 1 Health Booster, 1 Audio Log
From the start, make sure to grab the Audio Log - Bright 09 underneath the boxes to the left in the entrance area. Entering the main room, you should see Switch #1 (Red) directly across from you, above the exit door. Switch #2 (Yellow) is just to the right of that, up high in the corner. Continuing to the right, Switch #3 (Red) is just past the midpoint of the wall clockwise from #2, sitting between the center partition and a door with red lights around it. Right of that one, and higher up, you’ll see Switch #4 (Blue) way up high in the corner. You should also see Switch #5 (Blue) low and to the right from #4, just above some black spikes protruding near ground level.
Continue panning right (clockwise) from #5, and you’ll see Switch #6 (Yellow ) higher on the same wall, past the entrance door. Again continue to pan clockwise and you’ll come back around nearly full circle to see Switch #7 (Yellow) high on the wall to your left when facing the exit door, near that front-left corner. Switch #8 (Blue) sits in said corner up high, left of the exit door when facing it. Between switches #7 & #8, you should see the Yellow Key floating down closer to ground level, so just shoot it down. Wrap up the enemies under par time and you’re all set for this easy arena dungeon. The Health Booster is directly underneath the ramp leading down in the loot room.
House of Steel
10 Core Entry, 3 Prismatic Cores, 6 Supply Caches, NO Health Booster
Enter and head forward onto the central platform. Activate the console to your left to move the floating platforms into position to reach the doorway to the left (when facing the console you just activated). Before jumping across, look a few feet ahead to the right when facing the console to see Switch #1 (Red) on a rock pillar. Head across into the next room and deal with the flying enemies. In the next room with all the yellow bot alcoves, deal with the enemies first. Once they are all dead, return to the entrance door for a point of reference. Facing into the room from the entrance, look high to your right for Switch #2 (Red). Jump onto the small metal protrusion at the base of the wall immediately to the left of the entrance, and from there up onto the metal catwalk above.
From here, jump up onto a 2nd, higher catwalk/girder. Follow it around the room to the left (relative to the entrance) to find Supply Cache #1 as well as a Prismatic Core container a little further along. This is the one of only two times you will find a core outside the loot room in a challenge dungeon, the other being in Pit of Oblivion. Exit into the next room, and on into the next after that. In this room, you should see a metal girder on the left to use with the climber bot. Before doing so, look directly to your right next to the entrance platform you’re on to find Switch #3 (Blue). You’ll then need to time your climber bot usage on the girder to make it through an alternating blue force field, then past a couple more via platforming to exit this room. In this next room, you should see several bots with blue lasers connected to them. Look directly above the door through which you entered from the previous room for Supply Cache #2.
After extracting the door to exit that last room, you’ll find yourself in a hall with large blue laser grids. Take them out with charged shots and your companions. Before exiting this hall, look above the exit for Switch #4 (Red). You should now find yourself back into the large entrance cavern. Wait for the platforms to move over to you, then jump across to the center platform and activate the other console on the far side from the 1st one you activated after the blue Cell Bot powers it up. Cross the platforms once they move into position, and head into the next room. Pass through the halls and into a room with more alternating force fields and a climber bot girder. This one is trickier to time, but remember that you can hesitate in mid-air before your 2nd jump in a double jump in order to wait for the force field to be open for you.
As you enter the next room past those force field jumps, look up above the metal girder at the top of the room for Switch #5 (Yellow). Immediately after that, standing in the entrance to the next room, look up high nearby to the left to see the Yellow Key floating and shoot it down. Just like the room earlier, jump onto the small protrusion on the wall left of the door (when facing into the room) and from there up onto the metal girder/catwalk. Fallow it as it slopes up and to the left around the room to reach the key you shot down. Look straight out from this ledge where the key was, into the room, to see Switch #6 (Blue) on the far side, between two metal claw-like structures.
It might be hard to spot in the flood of light, depending on your contrast settings. Facing that switch, look to your right up here for a small ledge with Supply Cache #3 on it. The final three supply caches are in the loot room. Continue on, back out into the main room, and an orange Cell Bot will follow you and open the way forward. Head across the platforms and into the next room, where you’ll find Switch #7 (Yellow) hidden behind the girders, to the left of the exit into the following room. Carry forward through said room and into the large, cavernous room beyond, where you’ll face the dungeon’s commander. In this room, you’ll find Switch #8 (Blue) floating between the two large vertical rings high in the center of the room.
Obsidian Run
11 Core Entry, 2 Prismatic Cores, 3 Supply Caches, 1 Health Booster, 1 Audio Log
Once again, bring climber and flyer bots with you. At the very beginning, look to your left on the rocks for an Audio Log - Bright 05. From the start, aim up to the left through the upper-left blue portal to shoot Switch #1 (Red). Go across the right-side platforms and through the portal, onto the next platform. Jump to the next, and dash/double-jump/dash off it to easily reach the next one, in front of the next blue portal. Before jumping through it, aim straight ahead to shoot Switch #2 (Red). Jump/dash through that portal and a 2nd one just behind it to land on the platform directly over that 2nd switch. You should see two more portals in front of you before a rock island where the cave makes a left turn, with a moving platform between them. Jump/dash through the first and onto the moving platform between the two portals.
Instead of jumping through the 2nd portal, however, look up to your left to see the Yellow Key floating. Shoot it down and use attach to the climber bot girder to reach it. Jump down to the rock island at the cave’s turn, and look for Switch #3 (Red) behind the rocks on the far side from where you entered. Turn left 90 degrees to see a string of blue portals, and shoot Switch #4 (Red) to the left of them. There are five portals, and a mere dash/single-jump between each should suffice, with a jump/dash/jump after the last one to reach the next platform. Here, you should see a few more portals in front of you, and should be able to aim underneath the one on the right to shoot Switch #5 (Red), which floats just beside the 2nd portal, before jumping through them.
After jumping through those three portals, you’ll land on a stationary platform with blue arrows. Look ahead to the right of the next portals to shoot Switch #6 (Red). Jump through those three portals (two moving and a center stationary one) to reach the next rock island at another bend in the cave’s path. Looking ahead from here, you’ll see a series of five more portals. After passing through the 1st, once again a single jump/dash combo should suffice to get you to each of the next four, with a jump/dash/jump string after the last to land safely on the next stationary platform. On this platform, look ahead to your left for Switch #7 (Red).
You’re probably already nervous looking ahead to the next series, but it isn’t that bad. First, you’ll have to pass through three portals to a stationary platform. The nearest one moves forward and back, while the two behind it, before the platform, move up and down. You’ll see in the video I make a couple of mistakes here, and the flyer bot saves my bacon on one of them. For these first three portals, wait until the nearest one is moving toward you from its furthest point. Jump/dash through it, then jump and hang out mid-air so that you can dash back toward the screen, through it again. Once you pass through a second time, reverse course again and dash through it a 3rd time. You should be close enough to the two vertical moving portals now that it should be no problem getting through them to the platform. From the platform, look to the right near the end of the next set of portals to shoot Switch #8 (Red).
You can’t miss the Health Booster, as you land on its platform here. The next set of portals can be intimidating, but they really aren’t that bad. The key is not to try and plan your route BEFORE jumping forward and over-committing to a specific direction. It’s better to simply focus on the portal nearest you and jump/dash through it. As Joule approaches and hits the portal, be looking forward to the next two, which will always be moving in the same direction, but with some distance between them. Angle your next jump/dash so that you’re moving toward a location where a portal is approaching, rather than where they currently are when you hit the previous portal. After passing through two ‘pairs’ of portals, you’ll have to time your final jump/dash and angle it toward a lone final portal.
If you biff the final one, try to use the flyer bot at the very peak of your jump and you MIGHT make it to the exit. You’ll notice in the video for this dungeon that I actually failed twice in this area, once on the first set of three portals, but the flyer saved me, and once on the final set. The 2nd time I actually fell to my death, but luckily had shaved enough seconds off of my run that I still had time to finish, even with the fall. I didn’t shoot the 8th switch until after landing, so I had to quickly spin around and shoot it while walking backward across the finish line, lol. This particular dungeon is one of the two hardest traversal ones, so don’t sweat it if it takes you a little practice to clear it with all three objectives.
Pit of Oblivion
20 Core Entry, 3 Prismatic Cores, 3 Supply Caches, NO Health Booster, 1 Audio Log
NOTE: I believe the map screen may have a typo/glitch on this one after the patch. There are either only 2 supply caches rather than 3, or there are only 3 prismatic cores. I say this because the loot room has 5 total rewards. There is one prismatic core during the dungeon, outside the loot room. There are no supply caches outside the loot room. Therefore, there are only six rewards, meaning either 4 cores and 2 caches, or 3 cores and 3 caches.
I'm leaning toward the latter, because my map screen says 3/4 cores even though I got the one in the dungeon and got all 3 objectives completed. Keep this in mind, and don't kill yourself trying to find a 4th core. This is similar to the problem with Pylon 512's map display glitch after the patch, which is showing 1/5 cores for me instead of the correct 4/4. It worked right pre-patch, lol, so they must've messed it up in the patch.
Bring climber bot and ape bot for this one. Head down the initial hallway into the main shaft of the dungeon. This is a vertical dungeon, so reference points will be a little trickier. From the entrance to the main shaft, dash/jump 45 degrees to your right into an alcove on the right wall. Immediately turn around and face back into the main shaft. You should see a platform on the right going up and down, and Switch #1 (Red) directly in front of you in a small nook. Jump over to the ledge to the right of the moving platform, and onto it to reach the upper ledge of the central rock pillar. Go straight across the central portion to the platform opposite the moving one.
Turn around 180 degrees, facing back toward the moving platform that brought you up here. Look directly above that moving platform, behind a floating blue portal (which you only see a side view of currently), into an alcove for Switch #2 (Blue). Look 45 degrees to your right from #2, way high up into the corner to see Switch #3 (Yellow), which you can just barely shoot from down here. Turn left and jump over to the walkway against the wall, then up a couple of boxes to a ledge above. Facing out toward the floating blue portal, turn 90 degrees to your right. You should be facing back down the way you came, toward the boxes. Look up above, beneath a metal grating walkway, to see Switch #4 (Red).
Jump out through the blue portal and across to the walkway on the far side of the shaft. Make you’re your climber bot is active. Turn right 90 degrees and jump across to another set of boxes, as there is no need to land on the walkway below them. Look for a climber bot girder above you and attach to it via to carry you across to the next walkway. Take the very quickly moving platform to the right over to the next platform/walkway. You should now see a darkened alcove nearby to the right as you land on this walkway. You’re also now standing on the grating that was above the last switch you shot from below. This alcove also houses the blue switch that you shot as #2.
Jump into the alcove and drop down the shaft to get the Yellow Key, then stand on the green pressure plate and use climber bot on the girders to get back up. Facing out from the alcove, jump over to the walkway on your left and take the moving platform up. At the top of its path, jump back the way you came to land on some boxes directly above the platform you were on below. You should see some red lasers to your left. Look above them, beneath the walkway above, to see Switch #5 (Blue). The walkway above that switch has another set of lasers, and you should see yet another sloped walkway very high up above, on the opposite side of the shaft, with a 3rd set of lasers on it.
Look on the right end of that walkway, above the 2nd set of red lasers, where you should barely make out and be able to shoot Switch #6 (Blue) from down here. From the top of the boxes, turn back toward the direction where you rode the last moving platform up to reach the boxes, and jump over to a metal grating against the wall above. From there, jump forward to the next grating in the corner of the wall, and over to the alcove to the right of it. Step on the green pressure plate in this alcove, and quickly use climber bot on the girders above the nearby ledge to carry you up. Switch to ape bot at the top to activate the slam pillar in front of the blue force field to drop it, shooting Switch #7 (Yellow) above you here.
Once the force field drops, jump 90 degrees to your left off this ledge, down to a platform far below, making sure to use your double-jump just before you land to prevent falling damage. You should see two green pressure plates on the short ledge here. Facing out toward the main shaft on this ledge, activate the right switch first (the one nearest the climber bot girders) to unlock them. Quickly step on the left plate (the one furthest from the girders), and activate climber bot to carry you up them. If you were quick, the door above will be open and you will land in a room full of stone rubble and a stone ramp leading up.
Go straight ahead and shoot the boxes to reveal the green Cell Bot, then head up the ramp. Run over to the green circle on the wall so that the cell bot will make its way over to activate it. While waiting, turn and face opposite that circle, with the red-lighted door on your left, to see Switch #8 (Red) at the far end of this hall, up above. There is also a Prismatic Core beneath it, the 2nd of the only two cores available in challenge dungeons outside the loot room.
Head up the ramp, dashing out off the ramp and jumping back in if you need to go around the lasers. Activate the terminal at the top to start a platform moving. Quickly jump onto the platform before the lasers return, then use climber bot to carry you across the girders nearby. Run up the next ramp, dodging the lasers once more if necessary, and jump across to the platform by the exit. Before going in, turn around and look down to your right, underneath the ramp that led up here. You should see Audio Log - Bright 10 on a pipe beneath the ramp, near that final blue switch.

As soon as you enter the arena room from the dungeon entrance, look up to your left just inside the door for Switch #1 (Red). From this doorway, look straight out ahead of you for Switch #2 (Red) on the far side of the room, and Switch #3 (Red) midway across the room, on your left. If you can’t see the one on the far side, the middle blue floating portal is probably obscuring your view. You should also see the Yellow Key being held by some floating enemies high to your left, so shoot it down. You’ll have to take a brief dip in the lava to grab it. Just jump out quickly. Jump down onto the central landmass from the entrance and turn around 180 degrees, facing back to the entrance. Down low to the right of the entrance, by some blue crystals, is Switch #4 (Red).
Turn back around and look over the far side of the landmass on your left (same side as Switch #3) to see Switch #5 (Red) down by the lava. From the center of the landmass, look straight up above you into the hole in the ceiling for Switch #6 (Red). Just over the side of the landmass, floating up against it, you’ll find Switch #7 (Red) in the middle of the side facing the exit door. For the final switch, stand on the landmass on the side nearest the entrance door and face toward the exit door. Now turn 90 degrees to your right. On this right-hand-side wall, up high on the end of it nearest the entrance door, you should see Switch #8 (Red) floating up high, near the ceiling. The Health Booster here is down the ramp in the loot room, to the right of the prismatic core container.

Getting in here might be tricky for some. In the area where the dungeon is located, look along the northwestern wall for some climber bot girders that you can use to launch yourself up to the top of the tower. Once up there, finding the green Cell Bots on your way down through the platforms inside it in order to unlock the dungeon is almost unavoidable. They’re all inside the tower on platforms, with one near the dungeon itself. There are other ways to the top of the tower from outside, but that is the easiest.
After passing four rolling balls, look to your right for Switch #1. You’ll pass six more balls on flat platforms, and come to a few on sloped platforms. Look to the left end, underneath the 3rd sloped platform, for Switch #2. You’ll see Switch #3 at the end of this first tunnel, directly underneath the platform at the end. Starting the 2nd tunnel, you’ll pass several single-ball platforms, followed by a few double-ball platforms where both balls are rolling the same direction. Look on the 2nd of the three platforms with two balls on them, dead center, for the Health Booster. After passing these, standing on the platform with arrows and facing the next one with two balls rolling in opposite directions, look to your left for Switch #4.
Just past Switch #4, you’ll have to make it through three blue force fields, with rolling balls to serve as a nuisance between them. Once you get past the 3rd, you should see a yellow metal girder up high to your right, where the climber bot can take you as a shortcut. Midway across this, the Yellow Key is floating. You’ll need to use your climber bot to cross the girder, but jump backwards onto the platform to get the Yellow Key after the climber bot releases you. Just ahead of the key, you will have to cross a few L-shaped platforms running between blue force fields, while dodging balls. Switch #5 is in the corner to the left, between the 1st and 2nd blue force fields. After making it past the L-shaped platforms were #5 was, you’ll reach a large junction between the tunnels.
Before turning into the next tunnel, look high to your right in the corner of the junction for Switch #6. This next hall can be rather tricky. Most folks will want to make their way forward staying over the platforms as much as possible, and jumping from one platform to the next while staying centered. This is actually not the best way, and can lead to many deaths when balls drop out of the ceiling pipes unexpectedly. Instead, try to stay to the side of the platforms as much as possible while jumping. When crossing from one platform to the next, dash out to the side off the platform, then jump and reorient yourself. Dash forward after that 1st jump, then reorient to the next platform and jump over to it. This helps make timing the balls much easier.
As you cross the first few platforms, before you reach the area with all the blue force fields, you should see Switch #7 sitting underneath a horizontal platform with a rolling ball on it. When you reach the grid where two vertical and two horizontal force fields intersect, make sure to use your dash/double-jump/dash sequence to make it through the gap in the middle and onto the next platform. Keep an eye out for the moving blue portal beyond as you jump through, so that you can time your next jump to pass through it when it is centered between the two ball-dropping pipes. When you reach the exit ledge past that, turn around 180 degrees to see Switch #8 beneath the platform you just passed.

At the start of this one, stand still where you spawn in and kill the enemies in the next room. The timer doesn’t start until you enter that room, so you can save yourself the clock time ticking away while fighting them if you kill them from your spawn. Once they’re dead, head forward into the main fighting room. You should immediately see the Yellow Key on the far side, to the right of the exit door. Switch #1 (Red) is directly above the exit door. To the left of the exit, near ground level on the far wall, you should see Switch #2 (Blue). To the left of that one, above the Area 3 Fusion Reactor sign on the left wall as you enter, sits Switch #3 (Blue).
Facing #3, continue panning left to face back toward the entrance, and you should see Switch #4 (Red) up and to the right of the entrance door. Continuing left (counterclockwise) from #4, you should see Switch #5 (Blue) up high. Switch #6 (Yellow) is to the left of #5, up high beside the Area 3 Fusion Reactor sign on its wall. Once the enemies are dealt with, go to the side of the round platform nearest the entrance door. Look down over the ledge, underneath the entrance door, for Switch #7 (Yellow). Finally go to the far side, nearest the exit. Facing the exit, look over the ledge to your right, down below, to shoot Switch #8 (Blue). The Health Booster is hard to miss. It sits a few feet to the right of the final core container at the bottom of the ramp in the loot room.
Final Mop-Up
I've left a few achievements to the end here because you most likely unlocked them through the normal course of play. By now you should have long-since reached Joule's maximum weapon level, as well as getting a core bot to level 30, for Locked and Loaded as well as All Grown Up. If you haven't taken the time to go to the crawler and fully infuse your level 30 core bot so that all three of its stats read MAX, do that as well for Well Fed.
Once that's done, while still in the crawler, craft every part you can until you've crafted 50 of them to unlock Workbench Wonder.
You probably haven't earned 50,000 E-tuner yet, unless you roamed around the overworld a LOT or replayed dungeons extensively. The best place to grind this is The Warren. There are tons of tuner pickups inside, and you can net a few thousand or so speed running the dungeon. You may want to leave this until after the hunting challenges grind for the final blueprints, though.
Assuming you did a good job sweeping all the overworld maps while going for Prismatic Cores, Audio Logs, Health Boosters, and Hardware pickups, you likely got all the blueprints in the overworld. If you're here, then you also must have cleared all the objectives in the challenge dungeons to obtain all the blueprints there. That leaves only the hunting challenges. Each frame (K9, climber, ape, and flyer) has hunting challenges in the pause menu.
Focus on one at a time, because some will require that specific companion bot frame to kill a certain enemy type. If you are looking for purple enemies, there are specific locations on the map that one of each type will spawn. Warping to the crawler and back respawns them. A purple K9, for instance, spawns in the northwest corner of Lonely Basin, just as you enter the area. Complete all the challenges for one frame to unlock Big Game Hunter, and for the rest of the frames to unlock The Architect if you obtained all the supply cache blueprints in the game.
Congratulations on a somewhat grueling 1k! Not the hardest one out there by any means, but a bit tedious with the collectibles eh? I will try to record a video picking up all the Hardware pickups in shifting sands at some point, since it would be nearly impossible to write text directions for that. Thanks for using my walkthrough. Peace, love, and gaming!~Life
