While the mysterious “TF2 2012” surprise Valve has planned (most likely a new game mode involving team combat against a war robot, to be released alongside the final Meet the Team video, “Meet the Pyro”) remains to be released, possibly some time around summer, that doesn’t mean Valve isn’t going to be holding off on content. And they just proved that today, with a pretty important addition to Team Fortress 2 that might change the way it’s played for a while!
