The first add-on for XCOM: Enemy Unknown will be released next Tuesday, November 4 for $7 (UK price to be verified). The Slingshot DLC includes three council missions (you must start a new game to play them), as well as a selection of new hats, helmets, and armor decos. I played all three new missions earlier this week, and my preliminary verdict is: well, they're alright. Are they what we wanted, though?
Yesterday we let our speculation over XCOM's inevitable DLC run as rampantly as a panicked Sectoid, but 2K and Firaxis have their own vision for XCOM's post-release content. Today they announce the impending deployment of Slingshot, a tri-Council-mission campaign set in a besieged China featuring a new playable squad character, enhanced customization options, and a couple research shortcuts.
