Online multiplayer games for up to four players are supported via Xbox Live. This is also the first wrestling game to feature a countering system that incorporates a specific reversal for each and every attacking move.
This game also has the Create-a-Wrestler feature, character evolution, and other customization options. It contains the Smackdown and Raw arena plus certain PPV arenas like SummerSlam. Certain match types include First Blood, Hell in the Cell, Hardcore, and others.
