If you're up for some hardcore gaming (and hooked on Walking Dead right now), then check out Rogue Survivor. With plenty of things to explore, this roguelike sandbox game will definitely fizzle your brains and give you a good challenge. In Rogue Survivor you get no special skills or powers. You simply play average Joe trying to fend off and survive a zombie infestation. For every day you successfully fight off these brain eating creatures, you gain more skills and you level up. Basically, your main goal is to stay alive for as long as possible. Of course, you can always fork over to the other side by becoming a zombie and see just how many humans you can eat. Fun game that's well worth several hours of your day.
