Gun Monkeys is a Procedurally–Generated, Physics-based, Online Deathmatch platform game from multi award-winning indie dev Size Five Games. In Gun Monkeys, you'll take charge of a modern-day power company. In the distant future, a catastrophic experiment into Perpetual Energy obliterates all human life, leaving the world choc-full of free-for-the-taking energy, but unpleasantly lacking in people to take advantage of it. Your job as CEO is to send a legion of pleasingly-expendable monkeys forwards in time to collect Power Cubes and return them to present-day, all from the comfort of your PC.Go to: http://store.steampowered.com/ and download STEAM client
