The long awaited DLC for the Tony Hawk's HD remake is finally avaiable today on Xbox Live (400MSP), PlayStation Network ($4.99) and a Steam release in a few days.

Activision have summarised the DLC contents as:

"Tony Hawk’s Pro Skater 3 HD Revert Pack expands on the game’s winning formula with the inclusion of three levels from the original Tony Hawk’s Pro Skater 3 (Airport, Los Angeles, and Canada). Skateboarding legends Steve Caballero and Geoff Rowley make their return to the world of Tony Hawk games and James Hetfield and Robert Trujillo from Metallica make a surprise appearance as playable characters. The Metallica track “All Nightmare Long” has also been added. But perhaps most importantly for true fans, the Revert move makes its return for mindblowing combos. The combination of the Revert and the Manual in these classic levels will mean ludicrous high scores!"

However for those with no intention of buying the DLC, the Revert ability will be available to all as a game update
