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 Use these to try the latest features or check if a bug is obsolete. Do not install these on top of 1.0!

* Fix bug with all units' voxels flipped relative Y axis
Center of inverted unit become (7,8) and Volutar deducted that empirically and made dirty fix in commit#757d674 which (fix, not the whole commit) can now be reverted. Big units loftemps loading logic was inverted too, and I've added quick workaround to not break anything
