This open-world RPG is set after yet another zombie apocalypse. It's up to you to survive as long as you possibly can before succumbing to the open jaws of the decaying armies who are out to get you. You'll inevitably die, but it's a different sort of adventure than the third and first-person shooters on the list that display things right in front of you rather than using an isometric view. It's also a sandbox -- so when you're not running for your life, you can mess about with the tools right in front of you.
