X-Passes

The X-Pass input system by the X-Door.

X-Passes are an important component of the Decision Game. These six passwords are used to open the X-Door, which in turn allow the remaining participants to escape the Underground Shelter via an elevator in the Central Elevator Hall.

X-Passes are only obtained when a Decision Game participant dies - how they are killed doesn't matter, whether it be one of the Decision Games, murder by another participant, or suicide. X-Passes are read aloud by an intercom speaker throughout the facility along with the name(s) of the recently deceased. The X-Passes are also listed on a board by the X-Door so that if someone forgot an X-Pass, they wouldn't need someone to die again -- a generosity from Zero.

X-Passes appear to be character specific and depend upon who killed the person and how they killed them.

X-Passea are not verifiable unless they are obtained from the same timeline as they are entered in. Using X-Passes from another history results in a penalty.

As they are set by Delta, they indicate he is very knowledgeable about the Decision Game participants. He is aware of facts about them from the future and other histories, and even some things that the participants did not know about themselves.

Trivia

• It is unknown if there is a limit to how many X-Passes could be entered. If there wasn't and someone could enter in as many X-Passes by guessing, then simply inputting numbers would result in two X-Passes (Six and Five). Doing colors would result in two (Red and Blue). Also, if someone guessed an X-Pass and got it right, simply entering the opposite would often yield another X-Pass. For example, if someone guessed Love, then Hate would be another. Rich/Poor, Dad/Mom, Kill/Save are more opposite X-Passes.
• That said, given the penalty imposed upon C-Team for using passwords learned from another timeline as opposed to passwords derived after deaths in the current timeline, it is likely that guessing would not yield the desired result.
