I bought this game for only 10$, and I discover a masterpiece, i now have more than 50 hours in the game and I still find a lot of things to do, you can customize the zombies to make the game harder, you can add new maps, objects, cars with the mods, and it's not even the final game, the crators will add the multiplayer in 6 months (you can play in multiplayer but it's not the last version of the game), they'll add animals, a story mode, and they encourage modders to improve the game as they wish, this game is really really good, way better than a lot of AAA, if you like to survive and create your own story this game is perfect, but you have to accept your death, because it's the only end of the game, it's the story of your death, not the story of an invincible man, you're like Will Smith in I am a legend. And if you don't like the vanilla game there is thousands of mods which can make the game as you wish, it's the best time to buy the game, because a game like that should be worth at least 50$.
