Hey big mechs, what'cha doing over there on Xbox Live Arcade? It's so green over there. We have a party waiting for you, and your friends Psychonauts, Stacking, and Costume Quest are all here! Oh good, you're coming: Double Fine has announced (opens in new tab) that Iron Brigade (formerly known as Trenched) will be available on Steam next week, on August 13.
The once XBLA-exclusive is a hybrid tower defense/third-person shooter which takes place in an alternate reality version of World War I. The PC version will also include the DLC, Rise of the Martian Bear. Martian bears? Terrifying -- let's hope NASA's Curiosity continues to find rocks.
