The metal rooms are all filled with the after-projections of the N4's memories. They serve no more purposes.
However, the rainforest-biome-recorder floor allows one to change the weather inside the indoor-forest simply have one player set the terminal to "storm" and wait for lightning to strike the player carrying the crystal: NOTE: Without PHD or Juggernog this player WILL go down. With jug it removes almost all their health so make sure there's no zombies near by.
The charged crystal can be placed on the podium on the top of the building. Stand back as when it's placed it will begin to create QUITE the light show!
After it's been completed the voice will come on again: Identification required.
This step is crucial to be done right, as if you mess up, it can kill you right there and then.
Have player playing as RUSSMAN enter the easter-egg hub room. You will now have to input his code. HOWEVER, he does not have his code. Instead, have the other 3 players travel to the mush-room (get it? A room full of Fungi? ) and the other to the reactor. You'll need the nausiade perk for this. Simply have marelton misty and samuel get sick and look arround the nearby floors for the answers to the code (it will be a big glowing number painted on the wall) Russman will input the code
If by chance you get the code wrong 3 times, shutdown sequence is initiate: The power goes out in all floors and all the abominations are released.
If the player gets the code right, you'll make it to the final stretch.
Head to the bottom floor, under the building.
Connect a wire here, super easy step. This will activate the end-game mode: Meaning no player will have access to the wing suits, a red button appears on the top floor, and the sky goes blood-red.
Here's the deal, you've made it back up to the top of the building now, and there's a big activation sequence.
You need parts: A cable, a circuit board, and maxis's journal.
Maxis's journal can be found only by a member other then stulenger and is located wherever stu first goes down. So remember that! When the other person picks it up, they question stulenger and get very angry at him, even russman. This piece must be found first.
There's a circuit board which can be located in a lab, the wall will give way and the doctor who operated on misty will appear behind it. Misty will question marelton about it and he states he doesn't even remember. Russman and Stu will become skeptical of Misty.
The last thing is a cable found in russman's office (one of the first floors above spawn). The group will then question russman as well of how he's involved in all of this. He remains silent.
Return to the roof, and the previously shut shelter on the roof can be opened by marelton, whom the other 3 will question how he, a week and frail scientist, managed to survive a nuclear blast...
Build the last machine here: The aethershot.
Now for the TRUE final stretch: All the power is off in the building, this includes teleporters and perks. You must "crank" back the aethershot. Think of the whole building as a slingshot and the elevator that's been with you this whole time as the stone.
To truly crank it back, each player must descend the building, stoping at each floor to call the elevator. It's important to hit every one, it IS possible.
Should one reach the bottom and not all the buttons have been pushed, simply step into the elevator and it will take you back to the top instantly. Try again.
Once you've pushed every button, enter the area bellow the building, and have every player that wants to go, step into the elevator. The doors will shut and BLAST OFF! You're rocketed up and vanish on the top floor into thin air.
Samuel: Are we dead?
Marelton: Where are we?
Misty: Look! The elevator says....
Russman: Now that ain't possible, I've been of the highest ranking members in this building for years, there is no level 81!
Misty: Tell that to the elevator...
Now: Here's where the multiple endings come into play:
The ending where russman and stulinger kill Misty and Marelton:
-Richtofen's soul will be seen before you: Blue and almost like the avagadro or TABOO (Super smash bros brawl) in the way it looks. Simply take the crystal from the center of the room, and carry it over to him. This will reward you with the richtofen ending and the achievement. Richtofen is now all-powerful and both players and zombies have glowing blue eyes for a while. He of course will gloat and the player's voices will all be made for richtofen. After 5 rounds however, the building will erupt, shattering everything and richtofen will end screaming "NO! WHAT HAS HAPPENED?!?! NO!" (Cuts to black, Game over)
Misty and marelton kill Samuel and Russman:
-A simiar understanding only maxis's soul isn't on floor 81. It's in the easter-egg Hub. This will open a portal to argartha on the bottom floor, if one visits the area, a horde of zombies will erupt from the portal with red eyes.... Samantha is found by maxis... But she is already dead... The red-eye zombies are invincible. You eventually die, maxis ends the game screaming "NOoooooo!"
The easter egg before this was not completed: There is no entity to guide you now. You can pick up the stone, but you can't put it anywhere.
The "Real" ending: Both sets of characters survive.
Both maxis and richtofen appear on the map. Each will beg you to bring the stone to one or the other, regardless of who you choose in the end, you won't be able to give it to them. A red had will rise from the floor and snatch it. The zombies eyes will all then turn red and the building will begin to crumble. Richtofen will eventually snap back in and fight of some of the red zombies while maxis stabilizes the building. This gives time for all 4 players to get to the wing suits and glide off into the area where one first spawns. Once they do, the building crumbles behind them. The N4 still have the stone needed for richtofen or maxis's success. And zombies will approach endlessly. You can fight them off as long as you want... At the end of the day the red-eyed zombies get it and drag it down with your corpses which flash away.
Either way you finish the easter egg, the reward is the same: You gain access to the WWW computer.
If one returns to a certain floor, they will notice a set of computers. Richtofen's reward will glow blue, Maxis's Orange, The true ending is white, and the non-ending is just a green terminal. Each produces it's own reward: A set of unlock able clothing for greif and survival modes:
Richtofen: Russman outfit.
Maxis: Marelton outfit.
True ending: Samuel outfit.
Unfinished ending: Misty outfit.
Likewise, they also all give access to a new in-game weapon given to players when they kill an abomination:
The mini-raygun: It's like a minion mixed with a ray gun! Lasts 30 seconds!
To find out more about the map, you need to visit the map in either the richtofen ending or the maxis ending, before the building is over run. Simply find the video arcade and look at the screen, they will each say a set of letters:
M C O E I
I R N S A
Together these letters for "Micronesia" which is where we'll be going in our next adventure:
Island of the Dead
