Tony Hawk's Pro Skater HD on PC will, like the console version, combine the best parts of Pro Skater 1 and 2, meaning that you can manual in-between tricks. It will also feature new single-player modes like Big Head Survival and Hawkman, as well as new online modes like Big Head Elimination. Big Head Survival and Elimination task you with doing continuous tricks to prevent your ever-growing head from exploding, while Hawkman is a mode described in the press release as "Pac-Man on skateboards."
