The Double Dynamites is an excellent cooperative two-player shooter. It was developed by Seibu Kaihatsu and first released into arcades in 1989. Fabtek released the game in North America.
The Double Dynamites is a bit like a third-person Operation Wolf, with continual scrolling, lots of shooting, lots of carnage, and lots of explosions. Each player is represented as a see-through torso, with guns blazing, visible only from behind and from the waist up.
