Not so bad..
not so bad, only a few points
-sounds are repetitive, i mean, like the coil sounds the same as the mini gun and the other guns
-tho it is kinda lik the last stand, it has a better story, but you lack some "goal" in the game.
-the ragdoll effect is not too good, tho it had some funny effects
-hmm, a golden skull, some zombies on ur roof, and OMGWTFBBQ aliens?!? aliens arent rlly fitting in the story ;)
-it was pretty boring that the waves were so repetive..
Hope it helps!
