This game is fucking fantastic. "Hunter by day, prey by night" couldn't be more fitting. It took a little while for it to get going, but once it does, there are some proper WTF moments. The parkour is excellent, better even than Mirror's Edge, and that's the daddy of parkour games. The combat is oh so satisfying, I think last time I got a kick out of mashing someone's head into a wall of spikes was in the good ol' days of Mortal Kombat.
The amount of ways to kill zeds is endless, and I find myself running out of imagnation before I run out of ways to kill them. At night the real baddies come out, zeds that will make you shit yourself and run. God help you if you don't run.
I like that the emphasis is really on melee weapons. Yes there are guns in the game but not only is ammo rarer than hen's teeth, you get seriously penalised for using them - they attract more badass zombies. Noise has a huge role in this game. Not overbearing, but it does make you think for a second before doing things which is brilliant.
The story and characters are exactly what you'd expect from this game - cheesy and using every single cliche in the book. The story is quite frankly shockingly bad, although I only clicked after reading other reviews. Whilst playing, I'm simply having too much fun mashing zeds into walls and kicking them off high rises to even notice. My only complaint so far is that it is pretty poorly omtimized. My PC stutters a bit now and then, it's no game breaker but it always seems to happen at the worst possible moments.
That said, it would appear that they're addressing this. Here's today's update (for PC):
