This Easter Egg requires four players to complete. You can do the first step with one player, but step two must be done with four people. Each step will have short pauses between for dialogue between your character and the trapped character. You will need the following items:

Gersch Device
Matryoshka Dolls
Upgraded Ray Gun
Upgraded Thundergun

---

At the start of the game you will hear a voice asking for help. He asks you to repair "the mechanism." The Kassimir Mechanism is a metal pod looking thing near the Lunar Lander by the Stamin-Up machine.

---

Step 1 You need the Gersch Device from the Mystery Box. Take it to the area next to the PhD Flopper and Lunar Lander. To the right of the stairs is a blinking generator. Throw your Gersch Device near it to suck it in. If you throw it too far, it will disappear and you will hear a Samantha laughing.

---

Step 2 You must wait for a wave with Space Monkeys. Have each player wait next to each Perk-A-Cola machine, with the exception of the Quick Revive machine. When the round starts, a button will pop out of the wall near each machine. All players must hit the buttons at the same time. You will hear a beep if done correctly or a buzz if done incorrectly.

Step 3 This step requires the Pack-A-Punch room to be open. Make a crawler and take it far off from the room. This step requires about two minutes of standing. All players must stand in front of a clock near the Pack-A-Punch room. It will be right under where the rocket took off. The clock will start counting down when all players are ready. Players can still shoot if the crawler gets too close, but hopefully that doesn't happen. Once the countdown is complete, a Nuke Power-Up will go off, ending the round/wave.

Step 4 Have one person on the Lunar Lander, one person at the Starting area near the Lunar Lander, one person near the Sickle Lunar Lander, and one person near the Claymore Lunar Lander. The objective here is to collect letters in the sky that spell out L-U-N-A in that order. Activate the Lunar Landers in this order:

Start > Claymores
Claymores > Start
Start > Sickle
Sickle > Claymores

---

Step 5 You will require the Gersch Device, the upgraded Ray Gun, the upgraded Thundergun, and the Matryoshka Dolls. Head over to the Kassimir Mechanism over by the Claymore Lunar Lander. Throw the Gersch Device near the light that's shooting on the ground and start shooting the Ray Gun, Thundergun, and throw Matryoshka dolls inside the black hole. If done right, you will hear more dialogue, ending the Easter Egg.

There is no known amount of power you need. If you do too much, Gersch will tell you there was a power overload. If you did to little, he will say you need more power.
