A hero's work is never done. Although the Teen Titans eventually triumphed in their first GBA adventure, the Brotherhood of Evil has taken revenge. Four of the five Titans have been kidnapped by the Brotherhood's leader, leaving Robin to save each of his teammates from an unthinkable fate. Luckily, rescued team members become playable characters and, as in the original game, each has a unique special ability. Players can switch between unlocked characters on the fly, to make use of the best power for each challenge. Multi-path level design allows players to make it though each stage with any of the characters, but certain special abilities allow players to take alternate routes and find hidden bonuses.
