The International House of Mojo

Campo Santo's first game is called Firewatch. They've only been working on it since January, so there's not much revealed yet. All that is known is it's a single player first person mystery game set in the Wyoming wilderness, where your only emotional lifeline is the person on the other end of a handheld radio. There is no release date set yet, but Campo Santo announced that it will be released on Windows, OS X, and Linux.
