Tactical title XCOM: Enemy Unknown isn't launching until next week, but 2K has decided to try and get you hyped up early with a launch trailer now.
It does nothing for me personally as it features nothing but CG footage, representing roughly 1% of the actual game -- gameplay makes me want to buy games, if you know what I mean. Nevertheless it's cool enough if you can appreciate this sort of thing, and features a gigantic gun and aliens exploding and such. Check it:
