The latest promotion also revealed that legendary martial artist Bruce Lee has been added to the game's roster.

There are two ways players can unlock the founder of Jeet Kune Do: beat the career mode on pro difficulty or higher, or pre-order the game from participating retailers to unlock him from day one. Lee will be available to compete in the Flyweight, Bantamweight, Featherweight and Lightweight divisions once unlocked. International retailers taking part in the pre-order deal will be announced soon.
