Two years after the original, Gungrave, and just approaching of that game's anime spinoff, Gungrave: Overdose was released. Preserving Yasuhiro Nightow's flair and artistic style, this outing adds new playable characters to the series and a new story, in which Grave resumes his tale as an unlikely anti-hero tracking down a sadistic druglord.
