Recommended Mods
- A Patcher: Fixes bugs and can unlock incomplete parts of the game. Effectively XcomUtil from earlier games remade for Apocalypse.
- RoadWar: Rebalances the vehicle combat, adding more game emphases to it.
- Karadoc's Apoc Mod: Rebalances tactical missions, can make the both more fair and challenging.
- Additional mods and other files for Apocalypse can be downloaded at StrategyCore here.
OpenApoc
An open source reinterpretation of the game's engine that's currently in a pre-alpha state.
Further details can be found on the project's official website, GitHub repository, and project forums.

Issues fixed
X-COM asks for CD
- The Steam version sometimes asks for the CD, preventing progress.
Extract folders from cd.iso and place them in the game's directory folder[3]
|
- The Steam version is set to "Minimal Install" in order to conserve space. The installer on the ISO can be used as an alternative, overwriting the existing installation with the "huge" setting.[4] Certain files, such as the music and videos, will still remain on the disc image, however, so they should be copied to the appropriate subfolders.
|
Use a later version of DOSBox (0.74 or newer; Steam uses 0.72)[5]
|
Choppy cutscenes
Use DOS32A
|
Bind it to SMKP.EXE with the following command: sb /r Smkp.exe
|
Replace the builtin player[6]
|
Use this patch from StrategyCore user Bomb Bloke.
- Included Smacker Video player may hang in DOSBox. This can be fixed by upgrading it to the latest version here. Batch scripts may also need to be edited depending on the game's directory.
|
Black screen on startup
This game has issues with certain SVGA cards (both real and emulated). It can be fixed by using this patcher. Note hat tthis program requires Windows and will not run in DOSBox.
Game hangs after entering the Alien Dimension
Certain versions of the game shipped without the map files for the Alien Dimension. They can be downloaded here.
