Vice: Project Doom
Released in November 1991 by Sammy, Vice: Project Doom was one of the more criminally overlooked games on the NES. The game has it all: creative and superb-quality graphics and music, challenging and fast-paced gameplay, and even competent plot and dialogue. The stages have a great deal of variety as well, featuring platforming, top-down shooter, and rail shooter stages. The actual plot is about an escaped test subject who takes on a host of genetically engineered bad guys and eventually comes face to face with his own demons.
