Double Dragon is a 1987 beat 'em up video game developed by Technōs Japan and distributed in North America and Europe by Taito. The game is a spiritual and technological successor to Technos' earlier beat 'em up, Nekketsu Kōha Kunio-kun (released outside of Japan by Taito as Renegade), but introduced several additions such as two-player cooperative gameplay 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, as well as inspiring other companies in creating their own beat 'em ups.
