The mysterious “Zero” traps 9 participants within an underground shelter, dividing them equally between 3 wards that are connected to an elevator shaft in the middle. The only way out – passing through a locked X-Door to access the elevator. Six passwords are required to unlock the door, and each password is revealed only after a participant dies. Zero’s “Decision Game” will offer teams the opportunity to kill other participants through a variety of means to obtain the necessary passwords so they may escape.
