In the distant future, Dr. Sugar Brown: a well-renowned and famous scientist is determined to figure out on who the strongest fighter of history is and has gone to great lengths in order to finally gain the answer of his own question. Through the use of a time machine that he had built, Dr. Brown has brought together several of the world’s most powerful super heroes throughout each century so that all of them can compete and take part in a one-on-one fighting/death-match tournament that Dr. Brown has organized.
The tournament itself being used as a way to determine on who the strongest fighter of history is. Little does Dr. Brown and the participating fighters know and realize that an unknown threat is secretly watching them during the progression of the tournament and that this unknown threat could easily endanger them and the rest of the world.
World Heroes is controlled with three of the four buttons (“A” to punch, “B” to kick and “C” to throw) used along with an 8-way joystick on the Neo Geo MVS arcade cabinet. The punches and kicks have two levels, weak and strong. In order to get each strength with just two buttons, the punch and kick buttons have to be pressed briefly for weak and longer for strong. This same mechanic even can be performed with special moves.
The throw button C, if close enough to the opponent, grabs and throws the opponent across the stage; however, if holding the joystick in the opposite direction at the right time, the opponent would be tossed the opposite direction. Introduced in the fighting game genre by World Heroes are some abilities exclusive to some characters that were used in several later fighting games, such as multi-jumping using Hanzou and Fuuma, and shooting projectiles from the air using Rasputin.
