World Heroes 2 (ワールドヒーローズ2) is a 1993 fighting arcade game developed and published by ADK with the assistance of SNK (now known as SNK Playmore). It was originally released for the Neo Geo MVS arcade cabinet on April 28, 1993. It is the sequel to the 1992 fighting arcade game World Heroes, as well as the second title of the World Heroes series. It was even the first game with the "ADK" logo labeled within the game after the developer changed from its previous name "Alpha Denshi"; however, the "Alpha" logo was last used on one of the arcade flyers of World Heroes 2.

It was followed by a sequel released less than a year later titled World Heroes 2 Jet.

World Heroes 2 uses most of the elements of its predecessor, such as the same three out of four button layout, movements and motion commands performed using an 8-way joystick, and the "Normal Game" and "Death Match" modes. However, the "C" button can either be used to throw when close enough to the opponent, or taunt against the opponent. New additions include six new characters, new and modified moves and fighting statistics added to the original eight playable characters returning from the first World Heroes, projectile-reflecting, counter-grabbing and a slightly faster movement. There are fourteen playable characters in all.

In "Normal Game" mode, the object is to first defeat all six playable characters introduced in World Heroes 2, then defeat four of the original eight characters introduced in the original World Heroes chosen by the game randomly. After that, the player must defeat the two bosses, Neo Geegus and Dio to win the game. The rule in each battle against a character, like in most fighting games at the time of its release, requires the players to win two-of three rounds to completely win against the opponent. If the timer runs out before anyone is knocked out, the one with the most health in his/her lifebars wins.

In "Death Match" mode, the object of this mode is the same as "Normal Game" mode, but with new stages that feature new environmental hazards and a unique lifebar called the "seesaw lifebar". Unlike most fighting games at the time, the seesaw lifebar in "Death Match" mode has a different rule. If the player hits his or her opponent, the arrow on the lifebar will move toward the opponent's side at a distance depending on certain moves performed against the opponent. If the arrow scrolls at the end of the opponent's side, he/she will have to constantly press any button to stand up as fast as possible before the referee counts to ten. If the arrow is perfectly in the middle with the time running out, the battle becomes a draw game.
