There are eight stages in this game. The beginning stages consists of randomly chosen areas from nations of unselected fighters (assuming those fighters have nations). If Rabio or Lepus is chosen, all four rival nation stages become playable. After completing all rival nation stages, there are four more stages. Player and team-specific endings occur after completing the first loop. After completing the 2nd loop, the ending consists of all pilot pairs giving a speech, with the second pilot in the last pair giving a cheat code.
The SNES version adds hidden boss attack and time attack modes, and two hidden playable fighters, Rabio and Lepus (from Rabio Lepus, known outside of Japan as Rabbit Punch). The Japanese version does not use kanji in text as in the arcade version. In the SNES version, there are two stage loops, and the order of rival nations is fixed. In the second loop, the game's difficulty increased, except in the very hard difficulty, where the second loop is easier.
YouTube celebrity and famous author John Green, having coming across the game in the Houston Airport, mistakenly read the console title display as "Nerd Fighters" while filming a video post addressing his brother Hank Green on the popular YouTube channel Vlogbrothers on February 17, 2007 . "Nerdfighters" and "Nerdfighteria" eventually became the collective title of the Vlogbrothers' fan community.
