Rogue Survivor is a survival roguelike sandbox game with plenty of depth to explore. You are put in the role of an average person in the middle of a zombie outbreak, and must stay alive for as long as possible.

Each day you survive, you'll level up and become stronger - but tougher enemies will also appear. Apart from finding weapons and barricading yourself into a safe area, you'll need to make sure you have a good supply of food and perhaps some friends to help out. Before you play, you'll need to read about how to play the game by pressing H in-game, as there's quite a lot to it. Apart from playing a survivor, you can also play as a zombie and see how many humans you can eat.

The game is in the very early stages of development, yet there is still tons to see and do. There's a pretty nice guide to surviving your first week on the Rogue Survivor wiki, and there are forums where regulars frequently talk about their latest games. Note that you need to use the Num direction keys to play. Go give it a download. (Thanks Mark!)
