[Note: if you are ever needing a visual guide or are confused on what to do next, there is always the gameplay demonstration video, which includes a demonstration of the easter egg]


CRYOGENIC SLUMBER PARTY
- STEP 1: Have at least one Richtofen player present (not only will they be needed for certain steps later on, but they are also the only ones who will spawn with the Golden Rod).

- STEP 2: Turn on the power (after reaching the Moon). Sidenote: Make sure to let the 1st excavator (excavator Pi) breach the base. You will need this to happen for a later step.

- STEP 3: Find the cable (looks like a small/medium sized brown pipe on the floor) in 1 of 5 random locations in the labs (the area right after the pyramid/power location and has only one initial entrance). Be warned that the cable has exactly 1 spawn location situated directly outside the labs on the moon's surface next to some toxic waste barrels and within view of mulekick, so if you cannot actually find it *in* the labs, then check there.

- STEP 4: Acquire the Gersch Device or QEDs from the mystery box.

- STEP 5: Teleport to Area 51 and immediately turn to your right, look for the 2 panels on a shelf with a glowing orange light above them.

- STEP 6: Throw a regular frag grenade / semtex in that corner. This will knock the plates to the ground.

- STEP 7: Now throw your Gersch / QED at the plates. This will suck them into a black hole and teleport them onto the teleporter with you. (NOTE: the way this was done is very hacky, because it actually uses a soul box, so you will likely need to throw multiple Gersches so that the black holes last long enough to kill at least one zombie near the plates)

- STEP 8: Take the teleporter and leave Area 51.

- STEP 9: Plug the cable into the terminal which will be on the right-hand side of the Receiver Bay (the side that's nearest to Tunnel 11).

- STEP 10: As Richtofen, place the Golden Rod into the apparatus directly next to the terminal and begin interacting with the screen. Hold your use key and wait for the dialog to finish, then interact with the screen again and keep repeating until all the dialog completes. The screen will turn green and become uninteractable. Now collect the Golden Rod, which will be charged, turning blue and making an electrical noise. Richtofen will cheer as he grabs the device.

- STEP 11: Complete "Samantha Says" (the terminals near spawn with RGBY blinking lights)
[in order to complete "Samantha Says," simply observe the order in which the lights blink, then repeat that order. Every repeat will add a new step to the sequence, so for example: if you get a blue light, press the blue light terminal (which is shown at the beginning of the cycle, from left to right, the terminals are RED, BLUE, GREEN, and YELLOW), then after the blue light could come a green light, so then you would press blue, then green. Repeat the process until you've completed the same sequence 6 times without failure. All terminals will blink green several times rapidly and then cease blinking altogether. If you are playing as Richtofen or Nikolai, you will also hear a comment from your character about having completed the terminals]

- STEP 12: Find the hacker device (it can spawn in any 1 of 8 random locations in the labs, marked by clipboards). There is only 1 hacker per-game, therefore the first person to pick it up is the only person that will have it until they die or otherwise lose the hacker, at which point it will spawn again in a different random location in the labs.

- STEP 13: Hack the 1st combine button in the labs (positioned all the way to the left of the wall, where the 4 combine buttons can be found). This will unlock the next hackable button, which will appear as a green light coming from a scanner (do not worry, there is no time limit and it's not randomized, either). Hack the scanner and proceed to the next scanner (there are 8 total scanners that must be hacked, and it will be the same order every game). Once all 8 scanners have been hacked, return to the combine buttons and begin with the 2nd combine button to the direct right of the left-most button. Then keep going right as you hack the buttons until they all light up green (Richtofen will also make a comment on the successful final hack).

- STEP 14: Let the 1st excavator breach the base as previously mentioned. After it has breached, use the hacker to send it back. Go to Tunnel 6 and find the now-exposed Vril artifact / ball. Melee or shoot the ball to make it move. However, be warned that it will stop at certain locations, where it will need to be meleed or shot again in order to continue moving. At one point, it will stop above a radar dish, right above the Receiver Bay, which is when 1 of 6 special weapons will be required: Dual zap guns (in wave gun / 1-gun mode), a raygun, a QED (must actually land and explode near the ball), a Pack-A-Punched Python Snub Nose, an explosive weapon such as the Mustang and Sally, or a sniper rifle with a heavy penetrating ammo type like the Barrett 50 cal. Shoot the ball with any 1 of these 6 special weapon types and it will continue on the path, where it can resume being meleed and shot with regular weapons again until it eventually connects to the pyramid.

- STEP 15: Kill 25 zombies near the pyramid, specifically near the newly-sprouted tube. Do not worry about flipping any switches, those will handle themselves automatically.

- STEP 16: Wait a moment for the Samantha reveal, then kill 100 zombies (25 for each tube). Make sure the zombies are actually killed near the tubes, or their souls will not be collected.

- STEP 17: After Richtofen has swapped souls with Samantha, he will gain all perks on the map. This marks the end of the Cryogenic Slumber Party easter egg, but there is more after this. Be warned that at this point, he can still lose all of his perks after being downed, and will not be able to gain them back until the Big Bang Theory easter egg is completed.


BIG BANG THEORY (continued easter egg)
- STEP 18: Using a hacker device, go to the Receiver Bay and hack the terminal that Richtofen used to charge the Golden Rod.

- STEP 19: Go back to the pyramid and kill the astronaut zombie that spawns there. His death pop will dislodge the artifact and teleport it into Maxis' realm, where he will begin his calculations. Just be sure that you actually kill the astronaut while he is near the pyramid/artifact!

- STEP 20: Go back to the Samnatha Says terminal with the hacker equipped. Hack the 4 colored buttons in the order that they appear.

- STEP 21: All players (including Richtofen) will be awarded with every perk on the map, plus a bonus perk: Cosmonaut Colada, which will be in its upgraded form. All perks from this point on will be permanent and cannot be lost, even after being downed. Thus marking the end of the Big Bang Theory easter egg.
