Needless to say, the process for using mods will differ from game to game. But for popular games like Elder Scrolls, Fallout, and Dragon Age, we recommend using the Nexus Mod Manager.

Browse Nexus Mods for the mod you wish to add into Aliens: Dark Descent. Be sure to create an account first, and then on the mod's page, select the Download: Manual button to obtain the mod file.

Nexus Mod Manager, which allows you to manage and install mods downloaded via Nexus Mods for various games, has finally received support for Fallout 4.
