In addition to announcing the release dates in a release this morning, 2K Games also detailed several extras that the collector's edition of the game will be getting. Those who pre-order the will get the Elite Soldier pack ensuring access to a Classic X-COM Soldier unit, Soldier Deco packs and complete color customization for the game's armor sets. The PC version of Enemy Unknown will also be bundled into the collector's edition. If you just want the no-frills version of the new XCOM for PC, you'll have to buy it digitally from a digital distribution hub like Steam.
A new developer diary above shows the level of customization that XCOM: Enemy Unknown promises to offer to players, with bases that you'll be able to tweak to execute specific strategies. It sounds like 2K's dev team really want to honor the trail-blazing freedom that the original XCOM brought to gamers 15 years ago.
