Brilliant game. If you've ever played the likes of Dead Island you'll love this. There's a lot of running around, picking up any weapon you can find before clouting the hordes of zombies in the face to increase xp. The map is very large and there are numerous locations to explore, with crafting and healing items to find. Zombies can be killed in multiple ways, however given the fact that large groups of them tend to congregate all over the game is heavily centred on parkour, so there is a lot of climbing, running and leaping between buildings to avoid the zombies as opposed to killing them. Engage, and you're likely to perish quickly. And that is just in the daytime. Things change at night when the much faster and harder zombies appear, and if you're caught out in the open, well your chances of survival are slim to say the least.
A fab game, if not a little tougher than the Dead Islands.
