Mod DB now offers downloads of The Great Class Dash modification for Team Fortress 2, which converts Valve's teamplay shooter into a side-scrolling platformer. Word is: "Players will have the chance to play four challenging levels. Additionally, the levels are filled with class-specific obstacles, meaning all nine classes will need to be used to beat the game." They have a couple of trailers to show how this plays out, here's one on the YouTube. Thanks Morris via GameSetWatch.
