Where Does XCOM 2 Store Mods?
XCOM 2 Workshop mods download to the Steam workshop tree under app ID 268500, while manual mods go in a Mods folder you create. Windows and Mac paths.
Last updated
XCOM 2 pulls Steam Workshop mods into numbered folders under the workshop tree for app 268500, one number per mod. Manual installs skip that tree entirely and go into a Mods folder inside the game data, which you create yourself for each edition.
The saves post covers campaigns. This one covers the mod side. Enable the set in the launcher before starting, and never remove a mod mid campaign unless you accept a broken save. The 2K launcher must stay in the loop: mods enabled outside it never reach the game.
Where XCOM 2 stores this, by platform
<SteamLibrary>\steamapps\workshop\content\268500
Each mod gets a numbered subfolder matching its Workshop page ID. Manual mods go in <install>\XComGame\Mods (base) or <install>\XCom2-WarOfTheChosen\XComGame\Mods (WotC). Create those Mods folders by hand.
~/Library/Application Support/Steam/steamapps/workshop/content/268500
Same split on Mac: subscribed files under workshop content 268500, manual drops in the Mods folder under XCOM2Data/xcomgame. Copy workshop folders there if the launcher refuses to see them.
Frequently asked questions
Why do my mods list but not load?
Match the folder to the edition you launch. Base game mods go in XCOM 2\XComGame\Mods and War of the Chosen mods in XCom2-WarOfTheChosen\XComGame\Mods. Mods in the wrong tree show up but never activate.
How do I back up a modded campaign?
Copy the save folder from the saves post plus your Mods folders with the game closed. Workshop subscriptions re-download on their own, but manual mods only exist in those folders.
