Richtofen's Grand Scheme

Richtofen's Grand Scheme is the easter egg mission of the Zombies map, Moon. The grand scheme must be completed in order to complete the Cryogenic Slumber Party and the Big Bang Theory achievements. This easter egg is much less difficult than the Eclipse easter egg as it does not require four people.

Requirements

 * Minimum two people, unless you only want to get the Cyrogenic Slumber Party Achievement, this can be done on solo.
 * 2 QEDs
 * 2 Gersch Devices
 * Wave Gun

Step 1
Outside of the starting room are four computer terminals lined up near a cliff. Each computer represents a color (going from left to right): red, green, blue, and yellow. When the step is started, all of the computers will flash one color. The player must then use the computer with that color. The computers will flash again, this time with two colors, and the player will once again have to match them. This step will continue until all of the computers flash green and a message is heard. If the player messes up, the step is restarted.

Step 2
Proceed to the second floor of the laboratory. On a wall there will be four dim, red buttons lined up next to each other.

One of these must be hacked which will also cost 500 points. After doing so, you will have to search all 3 floors of the laboratory for four white panels with bright green lights above them, you must hack all 4 lit panels within 60 seconds or you will have to hack one of the red buttons again to restart the process, ultimately costing you another 500 points for each failed attempt.

Once you have successfully hacked four green light panels you must head back to the four lined up Red Buttons, you need to press all four of them and each one allows around 2-3 seconds to press another one, it is easiest to just go from left to right or vice versa rapidly pressing the 'use/action' button.

When the player(s) are successful, they will all pulsate red, and the various buttons around them will flash as well. Additionally, the middle circle on the symbol in front of the pyramid will now be indented.

Step 3
The player must then let an excavator breach tunnel 6. Immediately after, take the hacker back to the spawn area, and hack the excavator terminal. Somehow a carved meteor (the characters refer to it as the egg) must be moved to the pyramid. The egg is found near the M16. Once knifed, it will begin to float towards a satellite dish on top of the spawn. If the egg gets stuck, simply knife it again, and remember to open doors for it.

After it reaches the dish, shoot it with the Wave Gun to have it fall down and travel towards tunnel 11. Eventually the egg will get stuck in the railings near the Stamin-Up perk. To get it out, stand adjacent to the wall where Stamin-Up is located, and you should see an opening in the ceiling. Either throw a grenade, or shoot any projectiles that induce splash damage (such as Ray Gun shots). Then it will merge with the plate in front of the pyramid.

Step 4
A container will rise in the top right corner (if the player has his/her back against the wall) of the Pyramid, the player must kill 25 zombies near this tube and have their souls sucked into the tube. Zombies that are killed within range will have a red stream of dust emit out and into the ceiling. Enemies killed via nukes or Tactical Grenades do count.

When the tube is full it will make a sound, the player then pulls a switch that looks like the power switch on the left wall.

Step 5
The pyramid should now open and the player should see Samantha. All players will now receive a Death Machine for a total of ninety seconds.

At this point the player(s) will have the Cryogenic Slumber Party achievement.

Step 6
Go back to Area 51, and look to the right side of the teleporter. The player will see a beam structure with some plates stored on it. Throw a grenade and then throw a Gersch device. If done correctly the plates should be on the teleporter with the player, and the player should teleport back.

Step 7
The player should see the plates near the Quick Revive in the spawn room. The player must throw a QED Device on them, so that they move to the right side of the room, and stand upright next to a computer.

Step 8
Now the player has to look around the map for a lead pipe. It is long, curved, and silver, and is located on any floor of the labs. It may be on the ground, against a wall or crate, or inside any desk where the Hacker may spawn.

Step 9
Return to the spawn building, and locate the computer that the plates have moved to.Put the Golden Rod between the Plates, Have the Person playing as Richtofen use the action button on the computer to the left of the plates until a voiceover is heard; listen to this voiceover until it is done. The player will know when he/she is done when the computer stays green. Note that the screen will blink green once or twice before staying on. Now retrieve the Vril Generator.

Step 10
Go back to the open pyramid. Four tubes will appear, and the player must kill now 25 zombies by each. After all the tubes have been filled, put the Vril Generator in the slot in front of the pyramid. Samantha and Richtofen should switch souls. Have Richtofen/Samantha pick up the Vril Generator again and he should have all 8 perks.

After completion of this step, everyone will receive a gamer picture of Samantha.

Step 11
Use a QED on the circle in the pyramid dial in the power room to make the egg move again. It should launch over to the Samantha Says machine. Use a Gersch Device to move the egg again.

Note: Steps 11 and 12 are interchangeable, and may be done in either order.

Step 12
Play Samantha Says 3 times (one for each rocket). Unlike the first time, the game begins by showing you the first three colors, then four, and five on the last time around. This makes it much more difficult to complete. If you do finish it correctly, Maxis will say something and then countdown to launch the rockets at the earth. The Easter Egg is now complete!

Trivia

 * This Easter Egg cannot be completed entirely on Solo, but Cryogenic Slumber Party can be achieved. It cannot be completed on Solo because Richtofen doesn't have the Vril Generator. This is probably because if the Easter Egg could be completed solo, the player would never be able to die, having infinite Quick Revives.
 * After Richtofen and Samantha have swapped bodies, the player controlling Richtofen will now be Samantha in Richtofen's body.
 * The Demonic Announcer sounds like Richtofen after completion of the easter egg.
 * After the Easter Egg has been completed, Area 51 has a different appearance due to the Earth being hit by the missiles. There are loads of dust clouds throughout the place. The atmosphere also appears to have been destroyed in the explosion, as outer space can be seen instead of the sky. The Pack-A-Punch Machine and the Perk Machines appear to be completely unaffected by the explosion.
 * After the easter egg is completed, the color of the zombies' eyes change from yellow to blue.
