Gun Monkeys, the “procedurally-generated, physics-based, online deathmatch,” platformer from Size Five Games, has released on Steam for PC and Mac. It’s also 10% off. In the game, players control a modern-day power company where 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.” The player sends monkeys forward in time to collect Power Cubes and return them to present-day. Sounds zany. Hit it up through the link.
