the stage. This was added to create longer combos if the player has the opportunity, not for the sole purpose of inflicting more damage. A major obstacle in producing the game was Namco's idea to include game modes that allowed four simultaneous characters. This took major rework, especially for online mode. Director Yuichi Yonemori also noted that the team wanted to make fights faster while adding these new mechanics.
