1987 - Technos Japan Corporation / Taito. This game was one of the first co-op games i've played. I still can feel the pain in my right-hand fingers that reminds me the thousend times i've pushed that kick red button on the Double Dragon arcade machine. I remember my favourite weapon was the baseball bat. The soundtrak was not the main game driver, however the level1 boss stage music was kind of engaging. Here is my own re-engeneered version of it.
