Welcome to my Factotum 90 walkthrough!
In this game we move two robots through a giant ship to solve the mystery of the whereabouts of the crew and the mystery of the alarms ringing all over the ships. As you progress you need to solve little puzzles, each level harder than the previous one, explaining new mechanics as you pass them.
If you follow this walkthrough you will get all the achievements in the least amount of time. Please note that this is only an achievement roadmap, so this is not a full completion of the game. Rather we will go to the earliest point for a completion which would be level 17.
So, take control and robot away!
As the game explains only the basics, there are a few things that might come in handy.
Don´t think too complicated. The easiest solutions are almost always the right solutions.
Get familiar with the robots control and make sure you utilize his walking and quick turns since this makes some riddles easier.
Holding 
lets you crawl which is perfect for sections where you need to take it slow and steady, while holding 
lets you run which effectively can reduce your needed time for the game tremendously.
Start a new game
Level 1
Right from the start, press 
. Now keep spamming the 
button until you unlock the following.
Now choose your robot and spam the 
button until you unlock the following.
Now run forward and walk on and off the red button ahead until you unlock the following
Head now to the right and you will see a crate. Press
to pick it up and keep spamming the
button until you unlock the final achievement in this level.
Now all that is left is to finish the level. Pick up the crate and drop it on the red button to pass the obstacle. Enter the elevator to finish the level.
Level 2As the level starts, walk forward on the button and wait for the guy to unlock the second robot. Now walk with the second robot to the first one and approach it. You will see some speech bubbles. Step away from the other robot, then back towards him to pop another speech bubble. Rinse and repeat until:
Now we must make a path for the 2nd walker to reach the upper walkway. Push the button and get to the laser that is coming out of the floor. Stand on it and redirect it to destroy the barrels ahead. Get the second robot inside this area, redirect the beam near the second button and destroy the next 3 barrels ahead. Reload the level and repeat. Note that by changing just to the 2nd walker you will access the beam right away. Do this until you unlock the following.
Now all that is left is to finish the level. Do the same steps you did for blowing up the barrels (the second set by redirecting the laser) and walk through to the elevator to finish the level.
Level 3There are no achievements to be gotten here, so we need to finish the level. Have Bot-1 move forward and ride up the moving platform to stand on the red button. Switch to Bot-2, move it past the button, ride once more up to pick up the box and place it on the second red button. Head to the exit with both bots.
Level 4Head to the green button in front of you to the right, activate it with
and repeat the process until you unlock the following.
Now for completing the level. Use the console once more and use the Bot-1 on the first red button to raise a platform. Head to the other side with the Bot-2 and have Bot-1 stand on the other button to raise the platform. In this new area we need to get both boxes with Bot-2, so place the first box on the button up here to get the second box. Drop either one from up here on the unoccupied button and once the Bot-1 reaches the raising platform, do the same for the next button. Now you can board the elevator and finish the level.
Level 5
There is again a chance for an achievement here. Move forward and stand on the button to let the second bot activate the switch. Head through the barrier and move forward to the laser coming from the floor. You passed a crystal and you now need to shoot the laser on the crystal. Repeat until you get the following.
To finish the level we need to place Bot-1 on the button in front of the crystal and move Bot-2 to get the box. Place it on the button, split the laser again and power both machines now to lower the last barrier blocking the elevator. Bring both bots to the exit.
Level 6
Take Bot-1 to the right end of the walkway you start on and Bot-2 on the button to raise Bot-1. Leave the Bot-1 up here and continue across the liquid with Bot-2. Use the buttons up here to make a path for the Bot-1 on the other side. Once at the elevator, use the console to disable the barrier and use the button to raise the platform to the elevator. Enter the elevator with both bots.
Level 7
Turn around at the very beginning, ride up the platforms to the end and use the first button to your right to activate the next platform and reach the box. Use it on the second button and head for the elevator with both bots.
Level 8
Bot-1 uses the button ahead to let Bot-2 reach the warp portal. Head inside and keep going backwards until you unlock the following.
Stay on the other side of the portal and use the button to call a moving platform. Ride it with the other bot and once you reach a dead end, use the first robot again, this time on the other side of the portal. This will move another platform and therefore bring the second robot to the elevator which you now can board with both robots.
Level 9Bot-1 goes through the portal and use Bot-2 to push the left button to raise a platform. Step forward one square with the Bot-1. Now use Bot-2, in the starting area, to deflect the lasers to the left crystal which will move a platform to Bot-1. This will give Bot-1 a platform to stand on so you can reach another plateau. Move Bot-2 to the right crystal and deflect a laser in to it so Bot-1 can reach a much needed box (after transferring platforms a few times). Take the box through the portal and use this box on the left button in the starting area to lower the walls blocking the exit elevator. Move both Bots through the portal and exit.
Level 10Move Bot-1 on to the moving platform straight ahead and place Bot-2 on the immobile platform to the right of the moving platform. Have Bot-1 follow the path through the portal and across the platforms until you reach a button that raises the platform for the Bot-2. Have Bot-2 Stand on the platform in front of the button so when Bot-1 moves off the button then Bot-2 will be raised up to a higher platform. Have Bot-1 move on to the immobile platform that is facing a button on a higher platform. Have Bot-2 stand on the next button to raise more platforms and use the button on the upper ledge to bring the Bot-1 up here. The exit elevator is to the left.
Level 11Use the button to the right to make a bridge to the bomb (green box). Now pick it up and put it down to let it explode. Rinse repeat until the following unlocks. The explosion won´t harm you! (It is advisable to only drop 77 bombs because you will need 20 for another achievement and 3 to complete other levels).
To finish the level, with Bot-1 grab a bomb and head all the way to the last platforms to the right with both Bots. The second button to the right will move a platform that leads to the elevator. Board the platform with the Bot-2. Place the bomb on the button with Bot-1 and quickly make your way to the platform to reach with both bots the exit.
Level 12Have Bot-1 step on the button while Bot-2 gets across the platforms. Have Bot-2 go through the portal, turn right and grab a bomb. Take the portal back, and you should see a bomb hiding behind some ballast containers, so blow up the containers and grab the other bomb. Walk back to Bot-1 with this bomb, have Bot-1 cross the platforms while Bot-2 holds the button down and after Bot-1 is safe then have Bot-2 face away from the platforms, drop the bomb and hold
to run backwards across the platforms. Bot-2 can now go get another bomb from the newly exposed bomb tube, stand on the button so Bot-1 can get across the platform that moves. Face the button so the platform is behind you, drop the bomb on the button and quickly run backwards with
to get both bots on this side.
Level 13
Stand Bot-1 on the button to the left to get Bot-2 across to the containers on the other side. Bring explosives back and blow up the green goo (Organic Samples), reload the level, rinse and repeat until you unlock the following: (It is advisable to only blow up 17 since you need to destroy 3 more to complete the levels)
Once you blow up the last sample, bring the Bot-1 to the explosives. Destroy the barrels blocking the path, with either Bot, to reach the exit.
Level 14
Have Bot-1 get a bomb and move both robots to the right side of the map (not near the bombs). Use Bot-2 to activate the platform to reach the other side with Bot-1. Have Bot-1 stand in the laser and bounce it back to Bot-2 so you can use the laser to destroy the containers. Have Bot-1 climb the rising platforms ahead. You will see 2 organic samples you need to blow up and two boxes to your right. After you blow up the first sample, use to quickly get back to the bombs and walk another bomb up to the remaining sample. You will need both boxes to finish the level (placed on the two red buttons in the beginning) so you will have to walk both boxes back with Bot-1 by walking the boxes back to Bot-2. Once both boxes are on both buttons, have Bot-1 grab a bomb to blow up the containers at the end and walk both on to the exit.
Level 15
Enter the laser with Bot-1, and by walking to the right the light box will move too, so place the light box on the button. Cross the path, with Bot-2 and stand on the button. Have Bot-1 enter the laser again so the box disappears. Walk across with Bot-1 to the other laser. Walking on the left platforms, with gaps in between, you will drop down on to a button. It will raise the platform so use to run to the next gap and drop down. Run to the exit and repeat this with the Bot-2 so both reach the exit.
Level 16
With Bot-1 head all the way to the right, blow up the barrel with a laser and get the bomb (ignoring the button for now). Move back to the start and switch to Bot-2. Have Bot-2 stand on the button previously ignored to make a path for the Bot-1. Have Bot-1 blow up the organic sample, keep going forward and stand on the button near the exit. Switch to Bot-2, get again a bomb and go to the moving platforms near Bot-1. Put a bomb on the button, get over the platform it raises, and hop on a different moving platform. You will reach another light box area. Walk through the laser that is closest to the moving platform you got off of. Your ultimate goal is to move that hologram behind you by walking the light block in to the protruding platforms. Walk towards the protruding platform so the block is stuck and you get closer until it is 1 square ahead of you. Move towards the button and use that protruding platform to get the box diagonally to your right but still one square away. Stand on the lower platform in front of the button, wiggle till the block hits the button and run to the exit. This part may take a few tries but again the idea is to get the light box one square diagonally to your right. If you need more help use this video provided by The Hidden Levels
The end of the level can be seen 6 minutes into the video
Level 17
Once the level starts, drop down the platform to your right and rotate counter clockwise on the laser until you unlock the following
Here is part one of a video for 100% the game if you don´t want to follow a written guide, credit goes to the hidden levels for doing these.
Congrats on finishing this rather quick game. From now you can finish it up to level 30, but since the achievements are all won, this comes down to personal liking of the game :D
