Days Gone is an open-world game that puts you in the shoes of a bounty hunter trying to survive a landscape filled with marauders and vicious mutant "Freakers." While Freakers aren't technically zombies, they're a whole lot like them. Given, the developers did make a pretty big point of emphasizing that Freakers are alive, so think more "28 Days Later." Oh, and it's not just humans. There are some seriously frightening animal Freakers too.
Days Gone is driven by its open and dynamic world. Everything is about options, and the sandbox gameplay lets you spend your time how you choose. If you find the idea of exploring a post-apocalyptic world interesting, this one is worth a look.
