Pre-purchase the "everything explained in the title" game Mount & Blade With Fire & Sword by May 3rd and you'll receive two new TF2 hats: The Hetman's Headpiece for the Engineer, and the Janissary Ketche for the Spy, pictured above.
What else is up? This: SpaceChem, the game Robin Walker dubbed "pretty much the greatest game ever made," has introduced three new TF2-themed levels. Travel to Australia, solve puzzles and unlock achievements to receive the new craftable element Moustachium in TF2. Use this new element to craft special SpaceChem-themed items, including a fishcake. That's right: this marks the start of a trend we're all for: other developer working their butts off to make a promotion for us. "Put your feet up, Team Fortress Team," SpaceChem seems to be saying. "You let us handle this one." Don't mind if we do, SpaceChem. Don't mind if we do.
