Empire at War
The original game, played from its own data, in this tab. Point it at your copy once: it stays on this device, works offline after that, and nothing is uploaded.
Commander
The name other players see in multiplayer. Kept in this browser; the game's lobby can change it too.
Your game
This needs your own copy of Empire at War with Forces of Corruption (Steam or Gold Pack). Pick one way:
Installed game folder
The folder that holds GameData and corruption. It is read where it is each time
you play; nothing is copied.
Game archive
A copy of the game folder in one file, kept in this browser's own storage.
Mods optional
A mod's own folder, the one with Data in it. It is read from your disk each time you play;
nothing is copied or changed, and removing it here leaves the folder as it was. Mods are laid over the game in the
order shown, the last on top. A total conversion needs the whole game under it: the installed folder, or an archive of it.
