While the first Prince of Persia teased us with Xbox Live "Aware", Ubisoft recently revealed
that the upcoming sequel will feature actual leaderboards and downloadable content for two Xbox-exclusive modes: Time
Attack & Arena Combat. While it's fairly self-explanatory, Time Attack will feature a relatively short level, in
which the goal is to complete it in as little time as possible, while Arena Combat features an enclosed area in which
you must fight off three waves of enemies in the time allotted. One level for each mode will be packaged with the game,
while an additional level can be downloaded via Live. This is a nice addition, that will likely add a bit of longevity
to the game.
