The Xbox game?
Heh, yeah, that was fun.
My only real issue was the pacing was a little unrefined. Started off really strong, escaping the facility, discovering that you can essentially backfist anything into oblivion, and then it stalls for a bit while you're running around levels and, eventually, make it to the next set-piece.
Finally, I didn't feel entirely comfortable with the looking sensitivity, as there wasn't any setting I felt that worked, but that's a minor gripe.
I'd love to see some more.
