Quite good
This was quite a fun game. Nice graphics, nice sound selections and an interesting system for the inbetween level bits.
However, quite a few little anoying things that wound me up. I would aim right at their heads and it the bullets would usually go elsewhere, sometime at the legs of the zombie beside it. When your clip empties you have to wait until it's reloaded before switching weapon. I'd prefer it if you could switch weapon straight after you hear the click. The collision in that barracks is a bit off. It seems that when a survivor gets the last kill, the game doesn't proceed to the next level. Why was the M4A1 so poor? I spent most of the game with the uzi and breezed through it. In the middle of reloading if you hold down fire, the bullets count down anyway, despite the fact no bullets have left the gun yet. The survivors weren't really much help, and I don't think they had bullet trails. The first couple of levels are the hardest in the game! Once you find the uzi the levels become easier. There were dogs at the first half of the game and they disappeared for the rest. The ending was dissapointing.
Ok I've gone on a bit, the game itself was good fun, it's just I like to see more from a game that's currently number 1 in the portal. Good effort though.
