XCOM: Enemy Within

XCOM: Enemy Within is the expansion to the 2012 Game of the Year award-winning strategy game XCOM: Enemy Unknown. Enemy Within adds an incredible array of new abilities, upgrades and weapons to combat new enemy and alien threats. This expansion also introduces new maps and missions, new tactical and strategic gameplay, and new multiplayer content providing a fresh new gameplay experience.

Construct the Genetics Lab to physically enhance your operatives’ abilities including augmentations to the chest, brain, eyes, skin, and legs or build the Cybernetics Lab to enable the construction of the new Mechanized Exoskeletal Cybersuit, or MEC. The new MEC Trooper class has specialized abilities and each suit can be upgraded with new weapons including the flamethrower and grenade launcher. You can even give your operatives an extra tactical edge with new projects from your engineering team and the Foundry.

Adopt new tactics to counter the threats from two new alien types and a deadly new organization known as EXALT. You'll need to obtain a valuable new alien resource, known as Meld, to help counter the new threats. Secure it on the battlefield and use it carefully back at base to unlock new research and upgrades.

Cloak-and-dagger and intelligence operations provide new tactical challenges on over 40 new battlefields. Players can create a custom squad from a wider array of options and dominate your opponent in intense, one-on-one, turn-based matches.
