Hidden Features (OpenApoc)

OpenApoc includes an extensive debug and cheat system not present in the original game. Debug hotkeys are toggled with F1 in both the Cityscape and Battlescape. When enabled, various diagnostic and cheat functions become available.

Note: The "Show debug commands on screen" option in the More Options menu controls whether debug command buttons are visible in the UI.
