The crouch walking animations (and hopping over the fence at the beginning) look ridiculous, I swear the "physics" seem like they're on par with Tom Clancy's Rainbow Six from 1999. And like Tiberius said, the zombie AI is just re-fucking-tarded. They spaz out and literally jump 10 feet at a time. Seems just like the DayZ mod for Arma 2. The zombies zig zagging and flying all over like deer on crack was one of the main reasons I disliked DayZ. I grew up playing FPS games, and consider myself to be very good at lining up shots in any FPS I've ever played, but trying to hit the zombies as they run towards you was a joke.
Also, it's spelled DEV blog, not DEEV, so pronounce it correctly. mmkay?
