XCOM: Enemy Within

The XCOM: Enemy Unknown expansion XCOM: Enemy Within adds a host of new enemies and features, including the ability to use a robotic exoskeleton and genetically modify your squad. In case you missed our Gamescom preview on the expansion, Firaxis has released a narrated demo that covers some of Enemy Within's new content.

Lead designer Ananda Gupta narrates the action, which includes a glimpse of the new mech suit in action. When outfitted with the fearsome exoskeleton, players can chip cover entirely away – at the cost of a huge amount of ammunition. Once that ammo is exhausted, units aren't worthless; the suits allow users to pack in a tremendous punch, provided they get in close enough. When range is more tactically advantageous, genetically modified characters can bound up to high places and use otherwise inaccessible sniper perches.

XCOM: Enemy Within is coming to PC as a downloadable expansion, and on consoles as part of a "Game of the year" style retail release on November 12.
