Double Dragon is a 1987 beat 'em up developed by Technos Japan and distributed in North America and Europe by Taito Corporation. 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.
Home versions of the game were released for the Nintendo Entertainment System, Sega Master System, Atari 2600, Atari 7800, Atari ST, Amiga, Commodore 64, Game Boy, Genesis/Mega Drive and Atari Lynx, among other platforms during the series's height of popularity. A remake titled Double Dragon Advance was released for the Game Boy Advance in 2003. The NES version was re-released for the Wii's Virtual Console in North America on April 28, 2008 at a cost of 500 Wii Points. Nintendo also released the GameBoy version on the Nintendo 3DS Virtual Console in 2011.
Another remake has been released for the iPod Touch/iPhone mobile devices, which features brand new gameplay, sprites and animations, and music.
