Really fun game with unique combination of survival, stealth, exploration and combat gameplay.
Avoiding hordes of zombies or luring them like lemmings is a key feature that makes traveling through the the map very different to other open world games.
There are good rpg elements for upgrading and crafting gear and the gunplay is good, kind of similar to The Last of Us in the sense that you need to conserve ammo and mix up your tactics.
The only negative for me is that some of the melee combat animations are a bit lacking and some of the optional dialogues are a bit cheesy.
Overall a good.game. 7.5/10
