Back in the early 1990s, the now-defunct studio Microprose captured the imagination of nerds everywhere with a tactical PC strategy game called X-Com: UFO Defense. The game put you in control of a squad of human freedom fighters opposing an alien invasion by fighting harrowing tactical battles on randomly generated maps against unknown numbers and varieties of aliens. Then it had you take the spoils of war (namely, alien technology) and use them to research powerful experimental weapons to bring into combat. Years later, 2K Marin, the studio responsible for BioShock 2, is now working on XCOM, a first-person shooter that will attempt to include elements of that original game but will also focus on fast-paced shooting action and character-driven stories.
