OpenXcom requires a vanilla version of the original UFO: Enemy Unknown / X-COM: UFO Defense (any edition) with the latest patch. It is not compatible with other games in the X-COM series. If you don’t own a copy, you can buy it from one of these retailers.
Do not use modded versions of X-COM, as they may be incompatible with OpenXcom.
Check the Installation documentation for more details.
These builds are automatically generated from the codebase, so they have the latest fixes and updates as well as the latest bugs. Use these if you wanna live on the bleeding edge or to check if a bug is obsolete. Do not install these on top of 1.0!

Allow different cutscenes when aborting mission
The PlayStation version of UFO plays a special cutscene when a mission is aborted. This will allow mods to map a cutscene to this particular event.
