The upcoming Tony Hawk’s Pro Skater HD downloadable content pack, now titled the Revert Pack, recently failed certification. The team behind the game had the following to say on the game’s official Facebook page:

We’ve received word that the DLC needs more time in the lab before release. It will not be out before the end of September. As soon as we get a firm date we’ll let everyone know. Sorry to keep you waiting – we appreciate your patience!

The upcoming content adds three levels from Tony Hawk’s Pro Skater 3, two new skaters, and the ability to perform a revert in those levels.
