Requirements:

• 1 to 4 players
• Hacker tool equipement
• Wave gun
• Quantic Entanglement Device
• Gersh Device

Once the power is on, (see part above) head back outside the spawning room. On your right while facing the Earth, is an area with 4 computers.

Interact with them to start a memory game. The 4 terminals will glow one by one, showing you their color. Each computer will glow twice, so you can remember their colors.

Then, all 4 terminals will show you the same color. If it’s blue, you must interact with the computer that is linked with the blue color. Each time you are correct, the will glow green, before repeating the sequence, with one color added.

Do this little game 5 times. When they turn black, the step is done.

If you are doing wrong, they will turn red and the step will come back to it’s starting point.

Head now to the laboratories, up the stairs in the MPD room. Those labs are separated into 3 floors. On the second floor stands on a wall 4 buttons. ( on the left of the stairs leading to the third floor )

The first button to the left must be hacked for 500 points Doing so, you will have a limited time (about a minute) to hack 4 panels with shiny lights on them. There are 8 of them scattered around the three floors, but only 4 will glow.

The possibly glowing pannels are located:

• Three on the first floor
• Two on the second floor
• Three on the third floor

Once done, head back to the buttons on the wall. You must activate all of them very rapidly. Making it easier if you are 4 players. If you are alone, just move from left to right while pressing action.

If done correctly, they will all glow.

For this step you will need patience. Three excavators might randomly activate to approach and breach the integrity of the base. One of them, the excavator Pi (π), will try to break tunnel 6. Let it do so. Take then the hacker tool and use it on the affiliated console on the spawn.

Once the excavator is pushed back, head to the tunnel which just break. You should find lying on the ground, a dark metal ball. It is a Vrill Sphere. In order to move it, you will have to knife it. Follow the ball and keep knifing it when it stops. If it is stuck on a door, simply open it.

The ball will eventually stick on the antenna, on top of the spawn. In order to make the ball move on, you will need to shoot it down with the Wave-Gun.

Keep following the ball on the other side of the spawn. It will eventually stick again in the ceiling, in the room around Stamin-up. You will need an explosive (Ray gun / Nades …) to get it moving again.

The step ends with the ball fitting on the MPD’s front circular plate.

A glass container should have risen on the right side of the pyramid. You will have to kill 25 zombies near it, to fill the glass cylinder with their souls.

Once done a particular sound will play, and you’ll have to interact with the lever, on the right side of the pyramid.

The MPD will open, revealing Samantha Maxis which is trapped in the pyramid. You will also get a 90 seconds death machine, but don’t worry this was only the first part of the EE.

Teleport back to Area 51. On your right while standing on the teleporter and facing the PaP, you should see two hexagonal plates on a shelf.

Get them down with a grenade, then throw a Gersh device on them. If done correctly, they will be on the teleporter now.

Get back to the Moon, and throw a Q.E.D at the plates you just teleported with you. They will set on a machine near a computer, in a corner of the spawn.

Now you will need to find a grey cable. You can pick it up at any moment in the game no matter how far you are in the easter egg. It is commonly located in the laboratories on any floor, most likely in corners or near workbenches, beneath the desks where you can get the hacker tool, on the left of the door leading to the BioDome, or near the crates outside the labs, leading to Mule kick.

Now head back to the spawn area, and place the wire between thecomputer and the 2 plates you teleported steps ago. It is located in a corner of the spawning room.

The player beeing Richtofen will have to place the Golden rod between the plates, then repeatedly using action in front of the computer. Keyboard sounds will be heard, then a dialog will play. The screen will glow red then green a couple of time.

You’ll know when the step is complete, when the Golden Rod will glow purple. Pick it up.
