World Heroes Perfect is a 2D fighting game from Alpha Denshi and is the fourth in the series after World Heroes 2 Jet. The different fighting modes from the previous World Heroes games have been removed, leaving a standard best-of-three rounds fighting mode. Players can choose from all 16 characters from the previous World Heroes game.
The controls have been changed since World Heroes 2 Jet. There are now two punch and kick buttons each. Buttons A and B are light and medium punches, respectively, while buttons C and D are light and medium kicks. By pressing both A and B or C and D together, players can throw strong punches or kicks.
World Heroes Perfect adds a hero gauge to the series' fighting system. The gauge functions similarly to power gauges in other fighters, in that characters can charge up their gauges by attacking their opponents. Once a character's gauge is fully charged, he or she has several advantages in combat. That character will inflict more damage per attack and take less damage from attacks.
Additionally, the character can then use an enhanced version of one of his or her special techniques, doing more damage but also losing the charge from the hero meter. The game also has desperation moves for each character; when a character is severely hurt, he or she can use a desperation attack. But if that character also has his or her hero gauge charged, then the desperation attack will be enhanced.
