Casimir Mechanism

In Ascension, at the first round, Gersch can be heard asking for help to "repair the mechanism" as well to hurry as "she is coming". This is the start of a puzzle to "repair" the Kassimir Mechanismand free Gersch. The following items are required (note that they are all required at once):
 * Gersch Device
 * Upgraded Ray Gun
 * Upgraded Thunder Gun
 * Matryoshka Dolls

Node 1
This first task is relatively easy. A player must have the Gersch Device for this part. In the area where the MP5K and the PhD Flopper are, if one looks out from the map to the left of the MP5K, there will be rubble but there will also be what appears to be a power generator with a glowing white light. If the player goes into the PhD Flopper room to the far back, one can hear a high-pitched whistling sound. The player with the Gersch Device must throw it onto the generator (if it bounces off the generator it will be okay, if it lands too far away the Device disappears). The player will see the generator get sucked into the black hole. At this point, Gersch tells the player to hurry and continue as 'she is getting closer'. Then the player must make their way to the lunar pad closest to the Stamin-Up. In the corner of the lunar pad room, there is a large terminal with a bright screen. Again the high-pitched sound can be heard. The player should press and hold the "use" button to activate the terminal and the screen will show part of the Illuminati symbol. At this point, the pod should show one light after this node is complete.

Node 2
This step has to be done during a Space Monkey round with four players. Space monkey rounds occur every 5-7 rounds, but only if the power has been turned on and at least one player has bought a perk. When these rounds begin, four switches will appear out of the walls close to all perk machines excluding Quick Revive and Mule Kick. The switches are small red buttons that can be hard to notice due to the darker lighting during the monkey rounds. The locations of the switches are:
 * Juggernog - opposite of the Perk-a-Cola machine.
 * PhD Flopper - left of the Perk-a-Cola machine.
 * Speed Cola - on the other side of the door frame of the Perk-a-Cola machine.
 * Stamin-Up - left of the Perk-a-Cola machine.

When all four players have gotten to the switches, they must be pressed at the same time (give or take a second) a player can count down from three, alternatively the player can hold the use button by the button and it will just beep constantly. If it's done correctly, all players will hear a beeping sound, and the pod will have two lights on. If it was done incorrectly, all players will hear a buzzing sound.

Node 3
This node is simple. At the end of a round, a couple of slow crawlers should be left to prevent interrupting the transmission, as this node takes two minutes to complete. At this point, the player must have launched the rocket to open the launch pad and the room where the Pack-a-Punch Machine is located. The player must lead the crawler(s) as far away as possible to avoid interruption, preferably to Stamin-Up. When the players enter the launch pad, there is a clock on the wall to the left showing 12:00. All players must now gather in front of the clock located in the room just before the Pack-a-Punch machine. This will now start a 2-minute countdown. During these 2 minutes, all players must stay on the pressure plate, but can do anything such as shoot or throw grenades in case the crawlers get close. When the 2 minutes are up, if done correctly, there will be an explosion (as if a Nuke was picked up) ending the round. At this point, there should be three lights active on the pod.

Node 4
This is the hardest node to complete. It is highly recommended to leave a couple of slow crawlers in the end of a round, as doing this is the middle of a round can be very difficult. Several letters can be seen floating above in a random order. To collect these letters, the players must use the Lunar Landers, but the letters must be collected in a certain order (to spell "LUNA"). To begin, the players should have the lander ready at the spawn room. One player should stand on the lander whilst another player heads to the lunar pad near the Stamin-Up. That player must then call the lander at that point. The player on the lander will be flying over to the lunar pad where it was called but will fly into the floating letter 'L' and collected it. Again, a player must stay on the Lander whilst another player calls the lander back to the spawn room. This time, the player on the lander will collect the letter 'U'. Once again, a player stays on the lander while another player calls it to the pad closest to Speed Cola and Sickle. The player on the lander will collect the letter 'N'. Finally have one player on the lander whilst another calls it back to the pad closest to Stamin-Up. They will collect the last letter 'A'. This spells out 'LUNA'. All lights should now be active on the pod.

Note: It is confirmed there is no 'R' to collect. LUNA is 'Moon' in multiple languages.

Node 5
At this point, after finishing all the other nodes, head back to the pod, which should now have all four lights on. The pod is located next to the claymores in the Lunar Lander room next to the Stamin-Up machine. The player will hear the howling sound again. If the player looks carefully, there is a small glowing orb on the ground. The way to accomplish this task is to have one player throw the Gersch Device, then shoot the black hole with some Porter's X2 Ray Gun shots, and 2 Zeus Cannon shots, along with some Matryoshka Dolls.

After completing this task, Gersch thanks the players for freeing him. Each player will then be given a Death Machine that lasts for 90 seconds. Soon after, the screen will turn to black and white when Samantha screams (if the player listens closely, they can hear her say "Come find me" very quietly). When her scream ends, the screen goes back to color. The node puzzle is complete.

Trivia

 * The Kassimir Mechanism is apparently what sent the four characters to Siberia. It would appear it somehow overdosed the teleporter. This is hinted by Dempsey cursing Gersch.
 * Richtofen refers to it on Moon as he states that he will show Gersch how to properly build one
 * Completing the Kassimir Mechanism and Richtofen's Grand Scheme are the only ways to get a Death Machine that lasts for 90 seconds.
 * This is the only major Easter Egg that doesn't have a trophy or an achievement linked to it.
