Machine gun+Chainsaw+alien things+blood+good storyline= a kick-ass game!!!!
Ok, firsts things first. The storyline is great with a few flaws and unanswered questions but the graphics make up for that.
The weapons are sick. Not a lot of variety, but still a kick ass set of weapons. Any gun that has a chainsaw attached to it is just sick!
The graphics in this game are gorgeous using the Unreal Engine 3 and on an HD it looks even better.
The sound is fantastic. My ears are still ringing from hearin shotguns and machine guns going off and the sound of revving up the chainsaw. I couldn't even hear the background sounds or music.
The voice acting is pretty good too and the characters are insanely detailed and pretty funny.
I would give this game a 10/10!
