Frequently asked

How do I install OpenXcom Extended Coop Mod?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and OpenXcom all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download OpenXcom Extended Coop Mod safely?

From the author's own page on mod.io, which is where the data here is synced from. IndexGG never mirrors, re-hosts or repackages a file: every download button points at the original source, so you get exactly what the author published.

Which OpenXcom versions does OpenXcom Extended Coop Mod work on?

The author has not declared a supported version in the metadata we sync, so there is nothing here we can state as fact. Check the project's own page before installing it, and treat an old mod with no declared version as untested on modern OpenXcom.

Last checked 10 d ago against mod.io. We do not host files and we do not republish descriptions; every download link points at the author’s own release.
