A long time ago, back before Tony Hawk's Pro Skater HD was even released, developer Robomodo asked fans which Pro Skater 3 packs they would like to see as future DLC for the title.Since then, it has been confirmed that the Los Angeles, Airport, and Canada levels were chosen and that the all-important revert would be available in the DLC.Activision has been pretty quiet since then, only noting that the pack would release in December and will cost 400 MSP. Now, we have more screens and fresh details to share with you.Besides the reveal of the levels that are included, the DLC will also include new skaters, as "skateboarding legends Steve Caballero and Geoff Rowley make their return to the world of Tony Hawk games." In addition, James Hetfield and Robert Trujillo from Metallica will also join the roster of playable characters. Metallica's track, “All Nightmare Long”, has also been added to the game's setlist. Perhaps more exciting than any of the above is the announcement that, along with the release of the DLC, a title update will be available that will add the ability to revert to ALL stages. That's right, you can now take advantage of it in all of the game's core levels as well.The aptly named "Tony Hawk’s Pro Skater 3 HD Revert Pack" and the title update will be available on December 4th. As noted above, the DLC content will cost 400 MSP.
