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\
%USERPROFILE%\Documents\My Games\XCOM - Enemy Within\XComGame\SaveData\
macOS (OS X) ~/Library/Application Support/Feral Interactive/XCOM Enemy Unknown/
Linux $XDG_DATA_HOME/feral-interactive/XCOM/savedata/
Savegames will start appearing in the wrong order once there are around 100.
Having too many savegames can cause slowdowns, which can be fixed by regularly purging them.
Savegames are game localization specific. Hence they are not usable if language is switched after campaign start.
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.

  1. For some reason XComGame internally returns the arguments value with an extra ". Double quotes are a reserved character in all Windows file systems, so every CreateFile call fails.
