Cryogenic Slumber Party is a zombies-related gameplay achievement/trophy in Moon. It is related to an easter egg on Moon. It requires the player to complete a total of five steps to release Samantha from the pyramid. When the pyramid opens, all players will be granted a Death Machine for 90 seconds.[1] In Call of Duty: Black Ops 3, the same achievement is only 15g instead of 75g.
