I expected something really bad, but it was surprisingly good, yes its cheesy, but for people who are into gaming too its quite enjoyable, the entire movie follows a FPS pattern, even the story unfolds like a game. There's the dumb NPC s , the cannon fodder, the big bad villain in the end, and some surprises in between for the conspiracy nuts... it even pays homage to some games, like at one point the protagonist picks up a crowbar and says hes gonna go freeman on the zombies ass... and at many points it reminded me of Castle Wolfenstein... All in all it was a good time pass movie provided you are looking for pure mindless violence and fun.
