Game data[edit]

Configuration files location[edit]

System Location
Windows %USERPROFILE%\Documents\My Games\XCOM - Enemy Unknown\XComGame\Config\
macOS (OS X) ~/Library/Application Support/Feral Interactive/XCOM Enemy Unknown/
Linux $XDG_DATA_HOME/feral-interactive/XCOM/WritableFiles/
This game follows the XDG Base Directory Specification on Linux.

Save game data location[edit]

System Location
Windows %USERPROFILE%\Documents\My Games\XCOM - Enemy Unknown\XComGame\SaveData\
macOS (OS X) ~/Library/Application Support/Feral Interactive/XCOM Enemy Unknown/
Linux $XDG_DATA_HOME/feral-interactive/XCOM/savedata/
Having too many savegames can cause slowdowns, which can be fixed by regularly purging savegames.
Savegames will start appearing in the wrong order once there are more than or around 100 savegames.
If savegames are not showing when starting the game in Linux after playing it in Windows, go to the savegames location in Linux and change the name of the folder SaveData to savedata.
