How to Get the Chessboard Skin in The Outlast Trials

In The Outlast Trials, players can unlock the Chessboard skin by finding the hidden keypad puzzle in the Disrupt the Neighborhood trial.

The fixed Devil’s Checkmate code is 7453, which awards a Sleep Room chessboard cosmetic as a secret reward.

Clues for the solution are hidden across high school classrooms in two trials, letting players complete the puzzle without trial-and-error.
