Leviathan Main Easter Egg/Map Guide

A guide to the main easter egg steps of the new custom zombies map Leviathan, in the coming days it will be updated with more specific wording, images and full details on currently unknown steps. Please comment any feedback, corrections or questions.

Shield/Submersible Armarment

1. Shield Body (Biodome)
   
   
2. Pipe (Speed Cola)
   
   
3. Viewport (Rain boots/Reserve Soda)
   
   
4. Crafting Bench (I recommend above the labs and next to the biodome)
   

Poseidon's Wrath

1. Spear Head (Cafeteria/Juggernog)
   
   
2. Joint/Middle Part (Malkovich, i.e. the guy in the tube)
   
   
3. Grip (Outside Near Staminup/M16 Hallway)
   

I recommend building the Poseidon's Wrath at the crafting bench just outside of the spawn room of the cafeteria side. Located next to pipe #4 (and white valve after attaching it)

Hacker Locations

• The first will be located on your right when entering the labs from the outside area with speed cola
  
  
  
  
• The second is on the left side of the hallway beside the harpoon upgrade room when entering from speed cola
  
  
  
  
• The third is located on a cart at the end of the hallway when entering from the biodome
  
  
  
  
• The fourth is located in the room next to the harpoon upgrade room
  
  
  
  
• The fifth is located just outside the fourth location's room when exiting the opposite side as the harpoon upgrade room
  
  
  
  
• The sixth is located at the end of the hallway that branches off to the office with the skull and vrill device
  
  
  
  
• The seventh is located next to the door that Dr Zav is hiding behind on some crates
  
  

Harpoon Upgrade

After getting the Poseidon's Eye crystal (end of valve step) go back to the KT4 crafting bench in the labs to make the harpoon gun upgrade.

Free Gersh Devices and QEDs

The free Gersh devices can be acquired by hacking the wall of screens in the second power room above PHD for 1000 points then filling them up with souls.

After the soulbox has been completed a four digit code will be displayed on the screen. Go to the submarine and type this code in on the keypad, the free Gersh Devices will be located in the room with you.

QEDs can be gotten by typing "9355" on the keypad in the submarine (Can only be done after Vrill device has been picked up).

• One can be killed in the outside area underneath the cafeteria
  
• One can be killed from the platform just outside of the room with the second power switch (used in rainbow uranium lockdowns)
  
• Two can be killed in the outside area with staminup. One closer to spawn, the other on the other side of power
  
• One can be found roaming above tunnel 11 which connects the cafeteria and biodome entrance

Jumping Jack/Leaper Mask: Kill a certain number of jumping jacks (usually gotten by the end of the second jumping jack round if you escort Dr Zav and do first diver boss)

Gold ABA: Depressurize every possible area. Labs, Power room, AK74u/Simon Says, Biodome, Cafeteria, Tunnel 11.

Diver Helmet: Kill three divers with the harpoon gun

God Mask: Every player must finish all three challenges displayed in spawn (challenges can be hacked to alter the requirements)

Main Easter Egg Part 1, The Skull and One Inch Punch

Between rounds 5 and 7 you will encounter your first jumping jack round (if all jumping jacks are killed with 100% accuracy or no missed shots you will be rewarded with a free perk) after the round is over the last jumping jack will drop a max ammo and a key.

Go to the labs section of the map and find the office with a wheel chair and painting, go up to the desk and interact with the draw.

Pick up the skull inside and head to the biodome. Place the skull on the alter in the crypt area of the biodome and fill it with souls until a blue portal opens

Head through the portal and you will find yourself in an open room with 4 primis statues. Throw a grenade at each of them and the light shining above the statue will disappear. After all the lights are gone return to the centre of the room to interact with the glowing blue light on the altar to start the diver bossfight.

After all players interact with the blue light the ground will collapse beneath you and a cutscene will start. After the diver spawns in kite him around the room with the zombies while shooting him with a finite damage weapon (no zap guns/wave gun or harpoon). He will try to shoot you with his harpoon launcher which knocks you back if the projectile hits as well as having the ability to root you if you are knocked into a wall by the harpoon. After dealing enough damage he will go to the centre of the room, kill any zombies not behind a pillar and charge an attack like the Keeper from DE. Hide behind one of the pillars in the room until the energy blast is over. If you do not the attac will one shot you. The diver will be still be standing in the centre of the room now with a shield. After killing a short wave of jumping jacks the diver will return to his first attack pattern. Repeat till he dies.

After killing the diver go to the centre of the room to equip the one inch punch from the glowing orb. You can return to the biodome via a newly opened portal behind the diver's throne.

Main Easter Egg Part 2, Valve and Crystal (Poseidon's Eye)

In the labs across from the room where you find the skull there is a dented metal door, when standing near it a man inside will begin to speak.

After he finishes go to the AK74u room next to Malkovich (the man in the tube) and interact with the Simon Says computers. Each will display a number. Interact with the corresponding power box/wall panel. You can tell which computer matches which wall panel by the wire connecting them. For the purposes of the diagram lets call each computer from left to right A B C D.

Example: If my monitors read "2 3 4 1" I would interact with the panels in the order D A B C

After interacting with ever wall panel in the correct order go back to the computers and play simon says. After successfully completing simon says the monitors will show a four digit code, one number on each screen.

Go to pack a punch in the submarine and input the code on the number pad, if done correctly a door will open in the submarine to the cockpit. Inside pick up the valve and return to the map. Around the map there are are a number of places which say "valve needed" most of them are either steam traps or numbered pipes. The pipe number and valve colour do not change game to game. The valve colours and pipe numbers are as follows

• Valve 1, Green. Located near the B panel in the AK74u room
  
• Valve 2, Blue. Located in the cafeteria near the exit to tunnel 11
  
• Valve 3, Red. Located just outside the second power room/above PHD/above the button to release the mine for the uranium step
  
• Valve 4, White. Located just to your right when exiting the spawn room on the cafeteria side. Next to the crafting bench best used for the specialist
  
• Valve 5, Yellow. Located in the M16 hallway between power and the outside area with staminup, same area as the last specialist part
  

After attaching the valve to each of the numbered pipes make sure to spin them. Once all valves have been attached and spun go back to Malkovich and find the pneumatic tubes in one of the side rooms. Each pneumatic tube should have a numbered canister sitting beneath it. Take note of the colour and number of the tube and canister.

Go to the area between the labs and biodome and set the pressure of each gauge with the number of the valve pipe to the value shown on the corresponding tube (if the pipe numbered 3 had the white valve set the pressure to the number on the canister from the white tube).

Once all values are inputted correctly there will be an audio queue. Go back to the dented door with the man behind it, attach the last valve and spin it to make Dr Zav to come out. Follow him while protecting him from jumping jacks and zombies until he reaches a door in the PHD room. He will open a door containing the crystal or Poseidon's Eye.

Main Easter Egg Part 3, Malkovitch and the Strange Rock (Uranium)

Around Malkovich's tube there are four terminals, interact with whichever one has the prompt to initiate link and then hack it with the hacker from the labs.

Once the terminal has been hacked you need to find the corresponding button around the map. They look like the ones from moon during the step where you need to hack the buttons in the labs. The active button is signified by a flashing light and a distinct audio queue. There are 7 button locations (More will be added after locating).

• In the AK74u room right next to Malkovich
  
• At the end of the M16 hallway where the specialist handle part is located
  
• Outside the biodome exit which faces labs
  
• In the PM63 room next to spawn
  
• In the same room as the desk with the skull
  
• In the room next to the cafeteria with the M16
  
• Near the underwater rocket pad near PHD

Once all the terminals have been hacked and activated return to Malkovich. After his dialogue finishes go to the room between the labs and PHD and press the button that gives you the prompt "release mine".

Go to the jump pad beside the rocket storage facility and underneath the cafeteria, there will be a sea mine just outside of the map. Shoot it when the second submarine comes close to it.

After the submarine has been shot down there should be a large white rock of uranium sitting on a crate just outside the door to PHD.

Pick it up and make your way back to Malkovich. The Uranium will explode if exposed to a pressurized environment for too long. In order to make it all the way to Malkovich without it exploding the tunnel between cafeteria and the pressure valve area must have been breached by the excavator. As well as either the AK74u room or biodome. The excavators all have codes to activate them that can be inputted into the submarine. The three codes are "2473" for the tunnel 11 excavator (hallway from cafeteria), "0743" for the AK74u room and "0439" for the biodome.

Main Easter Egg Part 4, The Vrill Device, Rainbow Uranium and Lockdowns

Melee the painting in the room where you found the skull with the one inch punch to reveal the Vrill Device.

--=WARNING=--
Power will be off till the end of this step. Make sure you and your team are set and ready for the 4 lockdowns.

Go to the massive tank in the outside area with speed cola and interact with the button on the back. This will initiate a lockdown on the platform in which you need to kill zombies on the platform to fill the tank. Once the tank is filled press the button you used to start the lockdown, it will spawn a rainbow uranium rock and a max ammo. After after pressing the button the map's power will go out and you need to complete three lockdowns to restart it.

• One is located in the labs next to the harpoon upgrade table
  
• The next is in the room just before the cafeteria when approaching from spawn
  
• The last is located in spawn
  

Any button that has not yet been defended will emit a clear audio cue. After the lockdowns have been completed go to the room above PHD where a second power switch will be waiting. Interact with it to restore power to the facility and return to Malkovich.

Main Easter Egg Part 5, The Final Stretch (w/Perma Perks!)

After Malkovich finishes his dialogue obtain the QEDs and throw them at 3 boxes located outside of the map. One is seen from the platform just outside the second power room. One can be seen from the door that leads from power to the outside platform next to the jump pad. One is on the rocks above the play area near the rainbow uranium vat.

Once all the boxes have teleported away return to Malkovich and interact with the computer/desk on the side of him near the broken door barrier. Throw a Gersh device into his pod after he has finished speaking. He will tell you to take the Vrill Device and return to the surface via a submarine. When he has finished speaking pick up the Vrill Device. Make sure no one is down when you do so otherwise they will not be rewarded with perma perk perkaholic. Go to the submarine in the room between showers and the MP5K near spawn and interact with the button next to it.

Main Easter Egg Part 6, Leviathan/Kraken Boss Fight

For a weapon loadout in solo I recommend the upgraded Harpoon gun, MKII and HK or RPK. For Co-Op I recommend each player has a wonder weapon of some description, RPK/HK and at least one player has the upgraded balistic knives. The general idea is for at least one player to have a Wonder Weapon/Utility/LMG setup. Other utilities are guns like mustang and sally or crossbow, guns that can help you get zombies off you or give you a moment if you need to revive a teammate. Ammo can be scarce during the fight because of the limited drops and boss' huge health pool.

Two attacks to pay attention for are his one shot charge up and laser. When he pulls his head back he is either going to switch sides or charge up the one shot so pay attention and get to cover. His laser is indicated by one of the eyes on his head glowing orange. The laser will track anyone out of cover and apply a fire effect.

[Menthol Reward]

To escape the dome area after both excavators, use the submarine to teleport back to spawn and hack the excavators for full access to the map!

[Umar Nurmagomedov]

giant map flaw is my teammate being stuck around the dome area with both excavators active, fix this.

[Tiger X Light]

how on earth are you supposed to get back to spawn if all the excavators are on? BAD GAME DESIGN

[FloatinJuice]

9327 is a free weapon I believe

[Friday]

I'll edit the guide to reflect the error, thanks for mentioning!

[samanthers]

I like this guide better for this one but let me clarify 2 things for people who decides to follow this guide and come across this comment

Shark mask - you need to kill a 6th shark kill which can be found roaming above tunnel 11 (the tunnel that connects cafeteria and the entrance of biodome)

Bonefire sale code: 7225

good luck gang.

[S!r Aske]

that one shot attack has gotta be the most bullcrap things ive ever encountered, 3 hours of EE and just get obliterated. me and my friend are both in cover behind the crates in the middle and get obliterated

[casey]

NOTE ABOUT THE LOCKDOWN STEP:

If for some reason you can't activate the backup power switch on the Lockdown step, it means you failed one of the lockdowns. The map gives zero feedback on if you fail besides a glitchy-sounding powering down sound, but you'll know you've successfully defended one of the terminals because one Jumping Jack will spawn after both the first and second, and a Diver boss spawns after the third. If they don't spawn when they're supposed to, you failed the lockdown, and the only way to try that one again is to proceed to the next round, however, any lockdown that was successful will stay that way, meaning you don't have to do them all in one round, if, for example, you need to grind for a Max first. Proceeding to the next round will 'restart' them, playing their audio cues again if they aren't done yet. The map isn't bugged, it's just bad at telling you if you fail or succeed.

[サイクルは続く]

me and my fellow got stuck at returning on thee power it was not reacting after we contempt the contemptible locks

[Friday]

Its been like a year since I played the map but im pretty sure (so long as you havent found a bug) and did everything the guide up to that point it should work as described.
