Locate, research, and retreat. These are the three ideas presented in the XCOME3 2010 debut trailer, a bit of footage that also dedicates a decent chunk of time to establishing the game's suburban 1950's setting.
== TEASER == 2K Games has been keen on pointing out that XCOM will lean on strategy moreso than traditional, run-and-gun FPS action. So it isn't much of a surprise to see that the publisher is continuing to push the strategy bullet-point, choosing to illuminate the fact that we'll be snapping pictures of foes BioShock-style, in addition to being told to simply escape effed-up alien encounters. But at the same time, it's awesome that these non-traditional and interesting mechanics are getting the spotlight. You go, XCOM!
2K Marin, one of the studios behind BioShock 2, are behind XCOM. It's now slated for a 2011 release and, for the record, those aliens look like a cigar smoker's boogers (or Venom).
