Hidden Features (OpenXcom)

There are many little interface extras hidden in OpenXcom that aren't really mentioned anywhere ingame. This page is dedicated to them.

See Options for settings and keyboard shortcuts.

General

• Use the mouse cursor and keyboard keys to move the caret on text fields.

Geoscape

• Right-click on arrows to set a value to minimum/maximum.
• Use the mouse wheel to zoom the globe and right-click to center it on a location.
• Click on a weapon during a dogfight to disable/enable it.

• Right-click a grenade during pre-battle inventory to prime it.
• Right-click the Zero TUs button to reset a soldier's time units (so they can't reaction fire).

Debug mode

Debug mode is a special feature that makes it easier for developers/contributors to test out game features without needing to play a new game from scratch. After setting "debug: true" in the Options File, you can enable it by pressing Ctrl-D in-game to access a variety of features:

Geoscape: Unlocks all research and shows globe country and region borders. Clicking on the globe returns the point coordinates. This option can be toggled, and toggles between showing country borders, regional borders, and mission zones.

Battlescape: Whole map is revealed and opening the inventory screen resets TUs. Clicking the map returns the point coordinates. With traceAI enabled in the config, AI behavior is revealed and logged. Please note, in debug mode QuickSave/QuickLoad feature in Battlescape are completely disabled.

Ctrl-V will reset visibility on all tiles, useful for observing LOS behaviour.

Ctrl-K will kill all live aliens in the mission (nothing will be recovered).

You can also press Ctrl-U or set "debugUi: true" to reveal the borders of the interface text, to debug translation errors.
