Double Dragon is a 1987 beat-em-up developed by Technos Japan Corporation and distributed in North America and Europe by Taito. The game is considered a spiritual successor to Technos' earlier beat-em-up, Renegade, but introduced several additions such as two-player cooperative gameplay (hence the title) and the ability to arm oneself with an enemy's weapon after disarming them. Double Dragon is considered to be one of the first successful examples of the genre, resulting in the creation of two arcade sequels and several spinoffs.
