We've covered the best XCOM 2 mods, but what about Firaxis' first fantastic foray into our favourite universe? Well, despite being a seminal entry in the history of turn-based strategy games, it turns out introducing user-generated content into the mix is a lot harder than we remember. The sequel had Steam Workshop support, so installing new mods was as simple as clicking subscribe and ensuring you have the necessary DLC.
XCOM: Enemy Unknown (and its expansion, Enemy Within) have no such support and require a more hands on approach, in some cases requiring you to voyage into your game files and change values and replace files. Don't worry: each mod on this list will show you what you need to do in the mod description - just make sure you read the instructions!
For a more in-depth look at modding XCOM, we actually recommend following the Nexus Mod's guide to installing mods. They summarize the process very well and all of the mods listed below are found on that site anyway.
