You are all in grave danger. The Discovery One's mission to Jupiter is on the verge of catastrophic failure. Attempting to shut down supercomputer HAL to prevent further malfunctions didn't go as planned.

This game is a 1 vs. many game, in which one player takes on the role of the rogue supercomputer HAL, who is trying to shut down the Discovery on its journey to Jupiter. The HAL player does this by adding Malfunction cards to the various systems on the ship with their HAL cards. The other players are crewmembers must navigate the Discovery One as they try to disconnect HAL using Logic cards. But watch out as HAL is always listening and will do everything they can to stop you. Who will survive to complete the mission to Jupiter, human or machine?
