Really not bad as people as making it sound to be

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.
