The best scrolling beat 'em up game... Ever! This game still holds the crown nearly 30 years later. I loved the arcade version. Huge characters taking up a lot of screen, the animation was very detailed for the time. Huge boss characters and a great soundtrack to boot.
The best home version was on the Sega Mega-CD as the graphics looked identical to the arcade and even included a new time attack mini game as well. Seems it also had the best music and exclusive new voice acting as well. I still play it on Xbox Live the double impact addition. Still waiting for something to better it!
