Love a lot of aspects of this game, almost all, but it's definitely missing a few things. For instance , if the world has gone crazy, people would have too. Eventually you would get groups of some pretty bad folks.. addings bandits or thieves or what have you would be a step up. Also, I don't see why you and a friend couldn't survive together, don't know why it's single player only.. and the ability to build your own base would be really nice. Also the crafting is a little iffy, I shouldn't need a work bench to make arrows or improvised tools. However.. All in all, a great game! Definitely worth it for those who enjoy pitting themselves against the unknown.
