METALLICA frontman James Hetfield and bassist Robert Trujillo are featured as playable characters in the upcoming "Tony Hawk's Pro Skater HD" action sports video game "Revert Pack" DLC. The pack will be made available on December 4 at $4.99 on Xbox Live, PlayStation Network and Steam.

Although it was previously announced that the revert will only be usable within levels from "Tony Hawk 3" — not on the existing "Tony Hawk's Pro Skater" or "Tony Hawk's Pro Skater 2" levels included in "Tony Hawk's Pro Skater HD" — that is no longer the case: a free title update for the game will allow players to use the revert throughout the game; the patch should go live the week the add-on comes out, according to Polygon.

"Tony Hawk's Pro Skater HD" launched in July, selling 120,000 units in its initial Xbox Live timed-exclusive debut. The game was later released on PlayStation 3 and PC.
