20 GB

That makes it bigger than 91% of Strategy games we have measured.

Leave at least 29 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

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.
