Double Dragon
The player character has a repertoire of fighting techniques at his disposal, which he can execute individually or in combination using the joystick and the three action buttons (kick, jump and punch). The techniques range from simple punches and kicks to more complicated maneuvers such as hair grabs and elbow strikes. If you are playing with another player, you can help the other player by grabbing your partner's opponent from behind. Be careful when doing this, however, as some opponents are able to do the same to players. The player starts the game with a certain number of extra lives and a life meter that decreases when he/she is hit. If the life meter runs out or the time limit reaches zero, the player loses a life. There is a small selection of enemy characters that the player will encounter during the course of the game. Some enemies carry melee weapons that can be knocked out of their hands and picked up to attack them. Available weapons include baseball bats, whips, throwing knives and dynamite; you can also find rocks, oil drums and crates in certain locations. The game is divided into four different stages or "missions" consisting of a city slum, a factory, the forest and the gang's hideout. The game usually ends when a single player defeats the final boss alone. However, if two players manage to complete the game together, they must fight each other to find out who will win Marian's affections.
Story
The player takes control of martial artist Billy Lee or his twin brother Jimmy (also known as Hammer and Spike in the additional materials for the American arcade version), who fight their way into the Black Warriors gang's territory to save their mutual love Marian.
