This is the main Easter egg for the zombies map zetzubo no Shima. It can be done with any number of people, though, I recommend either 2 or 3, as 1 is naturally challenging, and with 4 the boss battle becomes very hectic (and it's in a quite confined area). I don't personally find it be very difficult, as it is essentially just map completion, but there are some tricky bits to it, and it is quite a time consuming task. In terms of steps this Easter egg is pretty bare bones your objective is literally find 3 gears and use them to fix an elevator, which takes you to the boss battle (which is incredibly easy). Unfortunately getting these gears requires a number of things be built. You will need to have built:
-the upgraded KT-4
-the shield
-completed al challenges for every player
- the skull of nan- sapwe
-the gas mask
These are individually quiet hefty tasks, I'll go into detail on how to obtain them in this guide (otherwise I'd be done writing this in 5 minutes) but just be aware that all these things are required
Additionally, this map has a heavy emphasis on the new planting mechanic they added (it's fairly bizarre) a lot of challenges require specific plants to be made ( as well as for the Easter egg) I'll go over the specific plants you will need for the Easter egg parts, but understand that you may need to research how to obtain certain other items.
The key to this Easter egg is multi- tasking. This isn't linearly stepped like every other Easter egg. All items can be built at the same time and all gears can be found at the same time in any order. So it is important you don't end rounds unless you're certain there is nothing else you can do in the way of planting, building, or obtaining gears, otherwise you might find yourself on a very high round.
PrerequisitesUnlike most other maps, you must make sure that at least one player has the “anywhere but here” gobblegum. This is required for the completion of the Easter egg. Unfortunately, you need to have reached level 5 (I think, might be wrong) In zombies to be able to equip this. So if everyone in your party is under level 5 (whether you've barely played any zombies, or recently prestiged) you will need to play a few games to reach that level, then restart.
Besides that, there is nothing else required, however, you may find mega gobblegums beneficial to you for the boss fight (I like taking in After taste, which lets you keep your perks if downed and revived)
So with someone with anywhere but here on, start a private game of zetzubo no shima. This guide will be structured differently than most Easter eggs, because, again, there aren't really steps. I'll give you all the tasks you need to complete, but remember they can be completed in any order, and should be done at the same time.
Building the skull of Nan SapweThere is a kind of introductory step for this easter egg, which must be done prior to obtaining any gears, and the skull is required for it (as well as building a few other items).
It is quite easy to obtain thankfully. To start, save a zombie on round 1 and head to the challenge area (buy the 500 door to your right from spawn, and the 750 door directly across from it). This is where you will see all your challenges, which I'll detail later, as well, in the center of the room is a pedestal like thing which contains 4 skulls. Underneath these skulls is a unique symbol (changes every game). Your goal is to find the skull with the symbol that corresponds to 1 of 4 pedestals around the map, these locations are.
-In spawn, pretty hard to miss.
-Right in front of the propeller trap
-In the large room at the end of the bunker
-In the room left of the power switch.
So basically, you look at the symbol on one of these pedestals, run to the skulls, and bring the correct skull back, placing it on the pedestal. Doing so will spawn in some enemies which won't attack you, but will attack the skull. You must defend the skull for about 20 seconds from the enemies. If the skull takes too much damage it will break, and you will need to try again. The skull in spawn is simple, as its round 1 so the zombies only take 1 knife to kill. The propeller trap skull is a bit trickier, and you will want to have gotten a decent gun to do it, as spiders will spawn in addition to the zombies, and they will attack you, not the skull. The other two skulls have both zombies and thrashers spawn, the thrashers will attack you, but your best bet is to just keep moving and shooting all the zombies. Once a skull is finished, all the enemies will die, and you must bring it to where you originally grabbed it.
Doing all 4 skulls and placing them in their original pedestal will open up a secret room down a staircase right in front of you. Head down there and hold
on the skull in the middle of the room. This will instigate a number of keeper spawns (similar to the rituals in shadows of evil). You will be locked in this room during this, and need to kill a number of keepers to power up the skull. The keeper's have very little health, one knife will kill them so you don't need to waste ammo, this is quite easy, just keep moving. Once all the necessary keepers are killed the skull of nan- sapwe is your, and all players can get one. This works like the sword in shadows of evil,
will pull it out and it has a limited use, it is quite powerful though and can get you out a bind.
Initial step, mesmerize a wallThis is very easy step, and has to be done in order to get gears to spawn in the map, so do it as soon as you get the skull of nan- sapwe.
Head into the purple water room in bunker, and stand in the corner, you will see a small corner of a map on one of the walls. You need to pull out the skull and mesmerize with
this map for a few seconds. This will reveal a larger map. Now, without putting the skull away (and hurrying because the skull is on a timer). Run back to the exit to the bunker. While facing the exit, you will see a chained door to your left (its an elevator). To the left of this is a blank wall, again do the same thing, mesmerize the wall for a few seconds and it will disappear, revealing a small room behind it. In here there is a motor to control the elevator, which is what you put the three gears on. Step done.
ChallengesThis Easter egg requires every player have completed all three of their challenges. The challenge room (same as where the skulls spawn) has 4 vertical pillars in, with 3 symbols engraved into them, each pillar has a different players challenges on them, and you can't see your team mates challenges. So find your pillar and look at the challenges. They are ranked from easiest at the bottom, to hardest at the top. There are a total of 16 different challenges you could get and they all vary in difficulty. Completing each challenge will give you a reward depending on the tier (just hold
while looking at the challenge symbol to obtain it). The lowest tier gives you a free max ammo, the middle tier gives you one of a selection of guns (the brecci is probably the best, if you dont get the brecci just don't grab whatever it gives you and you can do it again once it goes back). The top tier will allow you to obtain a 5th perk.
Now, there are some challenges which you should avoid outright, as they can be very difficult. If someone has one of these challenges, it is best to just restart (sinse you are looking at challenges on round 1, this isn't that biog of deal). The ones you want to avoid are:
-Kill 3 zombies as they are mutating. For me personally, I don't find this to be that hard, but most people do consider it very difficult, it is best to avoid it.
-Kill 30 zombies with the propeller trap. This isn't crazy difficult in theory, the problem being the propeller trap is in a terrible spot, forcing you to basically trap yourself for a time in order to get kills.
Besides these two, the challenges are not that difficult, a few of them require you water plants in a specific way. I won't detail how to do every challenge here, but there are plenty of guides on how to.
Anyway, once all players have completed there challenges, it causes a lightning strike to periodically hit the area, which is needed for later steps
Building the ShieldThe shield on this map is very easy to build, unfortunately, unlike past maps, all it does is cover your back, no rockets or anything on it. There are 3 parts around the map located:
-In the blue water area, underneath the power room
-The area right before the green water, the open area in front of the power room
-The AA gun room (first right when entering the bunker).
Obtain all three pieces (they may change positions every game, but they are in the same general areas) and build the shield, in the green water power room, all players should grab one as it is good for covering your back, and needed for future steps.
Building the KT-4The un- upgraded KT- 4 is a decently powerful weapon, by itself, it is not really required, but you will need to upgrade it (which is kind of difficult) to do the easter egg.
The KT- 4 has 3 parts, which are fairly easy to obtain.
1. Spider venom: In the blue water power room, there is a cage which can be lowered using the button beside it. Lowering the cage will bring it underneath the area and open the cage. You need to wait for a spider round, and stand near the cage, a spider will walk into it and stay there. Now head back up to the power room, and raise the cage the same way you lowered it. A needles will take some venom from the spider, which you can now collect, very easy.
2. The flower: in the final room of the bunker, there is a door which you can see mule kick through. Enter it and turn left. There is a large path submerged in water. You must reach the end of this. Near the start, there is small pockets of air you can rise to use, but once the area turns kind of blue, there are no longer. At the very end of this tunnel is a flower, grab this, its the piece. Right beside it is a spore, which, when shot, will blow air bubbles for ou to breathe. Head out of there with the flower. This is quite easy to do once you know the tunnel well enough.
3. Green... thing: This one is simple, starting at around round 5, a zombie might spawn with a green glow about him, kill him, and he drops the piece, easy as that.
Head to the back of the end room of bunker, and you will see a work bench with a bunch of sciency stuff on it (note there are 2, but one is used for upgrading the Kt- 4. Hold
on this thing and it will craft for you the KT-4. Once someone grabs it, it will appear in the box, and everyone can grab it if they get it from the box.
Upgrading the KT-4This is much more of a challenge compared to just building the KT-4, but it is required to do this easter egg. As with the KT- 4 , the matsamune (thats what its called) requires three ingredients be collected, and then added to the KT-4.
1. Spider tooth:
This requires you have killed the spider boss. This is really quiet easy, and can be done on a decently early round. You really only need jug as a perk and a few decent enough weapons. You will also need the un- upgraded kt- 4 to get access to the fight. By the blue water there is a large spider web covering an opening. Shoot this with the KT- 4 and enter. The spider boss has a few attacks, but they're pretty easy to avoid. To kill it shoot it in its mouth when it is glowing yellow. It doesn't take long. The only challenge you face is potentially running out of ammo, the hit box on its mouth its quite small so you will miss many shots. It will occasionally spawn other small spiders, which stand a chance of dropping a max ammo, but for the most part you want to try and kill it before you run out. When you do kill it, you can walk up to its fangs and hold
to remove one of them, which is the part you need. As well further through the cave is a small body of liquid which will give you the perk widow's wine for free, and you can keep coming back if you down.
2. Skeleton tube... thing
For this one all players will have needed to do their challenges. Once this is done, have one player stand in the challenge area with their shield out (meaning not on your back). Eventually (no longer than 2 or so minutes) lightning will strike, and your shield will become electrified! This has its own benefits, for 1, any zombies which now hit you in the shield die, and, if you melee a perk machine with your shield it will cost half the price. Now, take the electrified shield over to the green water power room. In there, you will see a cage much like the one you trapped the spider in for the KT-4 part. This time, you can't hit the button to lower it however. You must melee the control panel with the electric shield, which opens up the cage, and walk in yourself. If you are playing solo, the cage will automatically lower and come back, but if not, another player needs to hold
on the control panel to lower you. You will enter this very bright confined space full of skeletons, one of the skeletons has a tube like thing its rib cage, grab it. Now have the other player hold
again to get you out.
3.Flower 2.0
This is similar to the flower from the first KT- 4, but more time consuming, as you are basically growing it yourself over the course of 3 rounds. You need special water for this however, rainbow water. To get this, you must take the sewer system from the end of the bunker to the green water (making sure you have a bucket), and holding
at the right time. You can't hold it the whole time, nor can you spam it, it can also be very difficult to see wehre you need to do it, here's what I do. When you enter the sewer your surroundings will be bright green, then as you proceed they'll quickly change to blue, then back to green, then blue again, you need to hold
as soon as you enter the second blue area. Doing this got me it every time. You can keep doing this to refil your rainbow water as often as you like, but for this piece, you basically need to water a specific plant 3 times (once per round) with the rainbow water. The plant in question is at the end of the water tunnel, where you obtained the plant for the Kt-4. Opposite where the spore spawns, there is a blank wall. You need to mesmerize this wall with the skull of nan- sapwe to reveal a hidden planting location. Plant a seed here and water it with rainbow water, returning every round to re- water it. It is easy to drown here, so be careful, stamin- up lets you hold your breath longer, and don't forget to shoot the spore. Once it has been watered three times over three rounds, a flower will spawn which you can pick up.
Having got all three parts head to the same place you built the KT- 4, and opposite this area is another bench for upgrading it. You need a KT- 4 already to upgrade it. NOTE: It is very important that your best player grab the matsamune, unlike the KT- 4, only one person can have this. If they down with it's okay, because you can upgrade a KT-4 from the box, but, if the person with the matsamune bleeds out in the boss battle, you're screwed. There's no escape and no way to finish the easter egg, so you're stuck in the boss battle until you die.
Gear 1: Anywhere but hereNow I'll tell you how to obtain all the gears needed to fix the elevator. The first one is pretty easy, one person will require the anywhere but here gobblegum. After killing the spider boss, use anywhere but here while in the boss fight area. This will transport you to a normally unreachable room above the blue water power. There are broken dragon eggs lying around, and the gear is lying on the floor. Grab it, and get out of there using a ladder, gear 1 done.
Gear 2: ZiplineThis one is a bit more challenging, and you put yourself at risk by trying it. To start, one person will need to get an electrified shield, they, as well as one other person, need to stand by the bottom landing of the zipline (the door to the left of the power switch room). Now, if you see, there is a dock outside of the map, which you can't reach, you need to get to it by falling off the zipline. The theories simple, one person is on the zipline, and another hits the control box with the electric shield to toss them off. However, when you fall off, you don't carry any momentum, so it can be kind of hard to tell when to do it. What's worse, if you miss the dock, the person on the zipline instantly bleeds out, losing their perks and guns. So obviously you don't want to miss. Thankfully there is a pretty easy way to land safely everytime. Just make sure you use the lower zipline, and as soon as the person activates the zipline melee the box. The dock is pretty much right there so you can't undershoot it coming from the bottom, but if you wait just a split second too long, you'll die. Also if you're doing this solo, you must melee the electric box, jump on the zipline, then press
to fall off. Once on the dock, you will see the next gear plain as day sitting on the ground, grab it.
Gear 3: Shhotin' a planeThis one can be quite frustrating. To start, as soon as you reveal the elevator room, begin planting seeds and watering them with blue water and shooting them with the KT- 4 once a round for 3 rounds. You can, and should, have as many of these plants going as you can. Because you are looking for something specific, which isn't guaranteed to drop. After 3 rounds, the plants will turn into these these large purple pod things, which you can open. These can actually give you some decent stuff, but what you're looking for here is a large, very obvious artillery shell.
Once you get one, head over to the AA gun room in bunker (first right as you enter). You'll notice the large AA gun (I mean... obviously). Now this part is really fidgety. Your goal is to use the AA gun and the shell you just found to shoot down a large plane which has been flying over the map every few minutes. You need to first load the gun by holding
on the back of it. It is very specific where it wants you to hold
, so move around until you get it, you hear a faint click when it is loaded. What's annoying is you may think you loaded it but didn't, or vice versa, which could be bad because you might accidentally fire the gun when you thought you were just loading it. When it is loaded, you want to wait for the large plane to fly into its sights and hold
again to fire, it is pretty difficult to miss, the game's pretty generous. If you do miss, you will need to get another artillery shell from the plant. When you destroy it, pay close attention, because a smoking piece of debris will fly off and into somewhere on the map, this is the gear. Find it and grab it, and now you're ready for the boss fight!
Building the gas mask Something very important first is the gas mask, if you enter the boss fight area without one, you will slowly die. The pieces for the gas mask are:
-In the green water area
-By the propeller trap
-The area at the bottom of the zipline
As with the shield, the locations change, but they are in the same general area. Grab all these pieces and build it by the purple water. The gas mask isn't super useful until the boss fight, so don't bother with it until then, as well you definitely want a full one going in.
Boss fightHead to the hidden room in bunker you opened with the skull and place the 3 gears on the motor, which opens up the elevator. Before you go down though, make sure you're geared up appropriately. Everyone should have full perks and upgraded weapons (preferably shotguns) its smart to bring in some gobblegums too, andmost importantly make sure everyone has a gas mask, and someone has a matsamune.
Once you're all geared up, everyone jump on the elevator and head down. When you reach the bottom, there will be some vines in your way with glowing orange areas on them. You need to clear these using the matsamune, a regular KT- 4 won't work. Enter the room and you'll see the tree monster thing you'll be fighting, it doesn't start right awayyou need to shoot one of its 4 arms in the orange bit to start it.
As I said, this is quite an easy boss fight. Basically, a number of thrashers and spiders will keep spawning, so don't kill them unless you need to (thrashers can drop max ammo). The boss himself, Takeo, rarely attacks you, he sometimes will slam his arm in front of himself, so try no to be super close to him. To kill him, you need to destroy all 4 of his arms using the matsamune. The first one is free, so you really only need to destroy the other 3. Usually, he is invulnerbale, but after about a minute of running around the area, avoiding thrashers, the weak point on one his arms will be revealed, which you need to shoot with the matsamune (it dies almost instantly). So just rinse and repeat that for his 2 other arms. Very easy. Some things to keep in mind:
-Your gas mask depletes if you run into the gas the thrashers drop when they die, so avoid that as best you can, because if your gas mask does deplete you will slowly suffocate.
-Keep moving, in the same direction as everyone else. Don't kill enemies unless they are in your way, as it will just respawn. Be always looking at Takeo to see if you can shoot him.
-Th guy with the matsamune must live at all costs! If he downs, it is worth sacrificing yourself to pick him up, because only he can damage the boss. If he does bleed out, as I said, you're stuck in the boss fight with no escape (the door locks you in) unless you die.
Once you shoot the final arm, he'll die and a pretty interesting cut scene will play. The achievement pops as soon as this is done, and you get all perks.
This Easter egg is fairly easy if you know the map well enough as it is basically just map completion. It is quite time consuming, but not super difficult.
If you have any questions ask me in the comments, and good luck!
