Based on its big brother King of Fighters 98, R2 features a very tidy Making Mode to maintain interest. Basically you get issued a series of challenges in each match such as win within a short time or beat your opponent without being able to block. Success allows you to enhance your characters abilities for the next challenge such as special move power or ability to block. Such modes go down well once the main challenge has been mastered - no mean feat in itself.
