If you're hungry for more Tony Hawk's Pro Skater HD content, the "Revert Pack" DLC will be hitting next month -- a little delayed, but better late than never, as they say.
The pack includes the Airport, LA, and Canada maps from Tony Hawk's Pro Skater 3, in addition to skaters Steve Caballero and Geoff Rowley, and non-pro skaters James Hetfield and Robert Trujillo of Metallica, cause why the heck not? Also, Metallica's "All Nightmare Long" tune will be added to the soundtrack.
Whether or not you plan on buying the DLC, a free update will hit at the same time, bringing the "Revert" move to all, allowing you to chain together tricks even moreso than you can already with manuals. Note you'll be able to revert on all levels, not just the DLC levels as previously planned (no doubt this is part of the reason for the delay).
The "Revert Pack" hits December 4 on all platforms, and costs about five dollars.
