Dark Adventure is a dimetric action-adventure game produced by Konami that was released for the arcades in North America in 1987. It was the first arcade game by Konami that allowed up to three players simultaneously. The game was also released as in Japan and as Devil World in other countries outside North America, although these versions feature significant gameplay differences and only allow up to two players. Plot An archeologist named Dr. Condor discovers the coffin of a demon in ancient ruins. During a press conference announcing his discovery, he decides to open the coffin for the first time, only to be transported into another world alongside a reporter named Labryna and another archeologist named Zorlock. The three heroes must now fight their way out of the Devil World in order to defeat the evil Demon King who is keeping them trapped and return to the human world. Gameplay Dark Adventure can be played by up to three players, with a different character assigned to each control panel. Each character starts the game with a different default weapon: Labryna (the leftmost player) wields a sword, Condor (the center player) uses a whip, and Zorlock (the rightmost player) carries a spear. The controls for each player consist of an eight-way joystick to move their character and three action buttons for jumping, attacking and throwing dynamite. The dynamite throw button only works when the player has acquired the required power-up. There's also a map button that can be used by any of the three players. When held, the map button will pause the game and display the location of keys and exits in places explored by the player, although this function is not available in every area. The objective of the game is to pick up the keys and unlock exits until the player has reached the lair of the final boss. There are a total of 40 areas to explore. Enemy creatures include minotaurs, skeleton warriors, swamp monsters, man-eating trees, giant spiders and rats. The game features both limited lives and a health gauge system. The player's health will gradually be drained as time goes by, even when the character is not sustaining any damage from enemies. The player must pick up soft drink cans to keep the health gauge filled and prevent the character from dying. If the player runs out of lives, the character will drop every key
