In December, Rock Band 4 sent players into the apocalypse in a DLC collaboration with Fallout 4, and now those looking to get hyped with the announcement last month of Psychonauts 2, you can get some free costume items to make Raz proud.Harmonix revealed through Twitter that free DLC based on the cult classic Psychonauts will be coming to Rock Band 4 this month in the game's January update.The DLC will specifically provide players with Raz's flying helmet from the series, along with a set of sweet Whispering Rock T-shirts for players to wear in-game, as a collaboration between Harmonix and Psychonauts developer Double Fine Studio.Of course, this begs the obvious question: when do we get Brutal Legend DLC for Rock Band 4?Rock Band 4 is available now for PS4 and Xbox One.
