Pistol Daimyo no Bōken (ピストル大名の冒険 lit. "The Adventure of the Pistol Feudal Lord"?) is a side-scrolling shooter arcade game that was released by Namco in 1990 only in Japan. It runs on Namco System 1 hardware. It is a spin-off of Bravoman, as the titular character appeared in that game as a boss-type enemy. This game was never released in the United States, due to its slightly questionable content. Source: Wikipedia, "Pistol Daimyo no Bōken", available under the CC-BY-SA License.
