Pretty sick.
...In a good way! The graphics are very nice, firstly, and the animation is just as good. The gore is obviously the strong point is the art.
Though the gameplay does seem a little slow at first and slightly repetitive, it's pretty fun and kept me going for a while. It's quite fun upgrading your vehicle once you have enough RP points and just to see your vehicle with new stuff on it is pretty sweet as well. But one thing: no pause button? That was one of the first things a game should indefinitely have.
...On another, completely irrelevant note, and even though this sounds a little ninny, I do feel bad for running into/over civilians and soldiers. But I suppose it's their fault that they happened to spawn in my way at their own inconvenience...
The audio is fantastic. The music is great, the sounds are fitting, and the voice acting is actually pretty good.
The coding is great and it's very unique to see a Pseudo 3-D game like this on Newgrounds. It was definitely different from what I was expecting at first, so this was a bit of a surprise.
One problem though... it's a little laggy on higher quality, meaning either I need to upgrade my comp, or this was designed more or less for newer/newish comps, which not everyone has. It's probably the first, though. Also it does seem to have a few bugs here and there, but nothing too serious, really.
Overall, while the Pseudo 3-D effect is quite cool and provides an interesting gameplay experience, it's flawed in a few areas. Nonetheless, I enjoyed myself and must say this is definitely a contender for one of the best games of October. Though there do seem to be quite a large ammount of zombie games nowadays. :P
