Decent enough shooter. If a tad generic. One of the 360's launch titles. I remember seeing it being played early after the consoles launch, and subsequently got it on PC, but never got into it myself. Until now. The most memorable thing I saw at the time was the awesome opening where the aliens rip open the bar to the background music of "Don't Fear the Reaper". One of the best game intros ever. Fairly standard FPS action. The most remarkable things about it I would say are the amazing set pieces and architecture. Just ended up taking screenshot after screenshot of them. I was kind of tempted to scratch this one from my list because I didn't think it would really be worth playing. After having played it, I could have probably lived with myself having done that. Seems they really wanted a sequel and I have heard whisperings of it from time to time. But now, 7 years on and still no sequel, it seems unlikely to happen.
