XCOM: Long War is a fan-made partial conversion mod for XCOM: Enemy Unknown and its expansion, XCOM: Enemy Within. Almost every aspect of the original game is altered, creating a longer, more complex campaign that presents players with more strategic choices and customization options. Long War adds a significant number of new soldier classes, abilities, weapons, armors, and usable items, and also introduces new features, including soldier fatigue and improvements to alien units over the course of the game.

XCOM: Enemy Within is a non-console expansion pack for XCOM: Enemy Unknown, a turn-based tactical strategy game. The expansion adds the ability to gene mod soldiers to add to their powers as well as the ability to create MECs, powerful robotic soldiers. These new features are created by collecting a resource called Meld on the tactical battlefield. A number of new maps were also added to the tactical game, as well as multiplayer. The PC version of Enemy Within is an add-on that requires the base game Enemy Unknown. The Console version of Enemy Within is a standalone expansion that does not require the base game Enemy Unknown.
