This is a tool-assisted speedrun. For more information, see http://tasvideos.org/2481M.html Double Dragon 2 is a beat'em-up game starring Billy (or Bimmy, depending on the game version) and Jimmy Lee in a quest to get revenge on a gang for killing Billy's girlfriend. Their journey starts on city streets, but it eventually goes to a variety of places like a helicopter, a dark forest, a haunted mansion, and a final fight bordering on the supernatural. You must play the hardest difficulty, Supreme Master, in order to reach the true final boss. One interesting feature of the game is that some very powerful moves can only be used from a crouching position, usually after landing from a jump or getting up from a knockdown. This is why you see the player jump so frequently. This run by xipo plays the game with only 1 player. It is slower than the two-player run (http://tasvideos.org/1279M.html) largely because it can't use tricks like the two players hitting each other with flying knees. However, there are still some interesting tricks and strategies in this movie well worth watching.
