Race CL (1978) Speed Race CL-5 (1980) Super Speed Race GP V (1980) Super Speed Race Jr. (1985) Automobili Lamborghini: Super Speed Race 64 (1998) Western Gun (Gun Fight) His next major title was Western Gun (known as Gun Fight in the United States), released in 1975. The game's concept was adapted from a Sega arcade electro-mechanical game, called Gun Fight (1969), with the cowboy figurines adapted into character sprites and both players able to maneuver across a landscape while shooting each other. The game is historically significant for several reasons. It was an early on-foot, multi-directional shooter, that could be played in single-player or two-player. It also introduced video game violence, being the first video game to depict human-to-human combat, and the first to depict a gun on screen. The game introduced dual-stick controls, with one eight-way joystick for movement and the other for changing the shooting direction, and was one of the earliest video games to represent game characters and fragments of story through its visual presentation. The player characters used in the game represented avatars for the players, and would yell "Got me!" when one of them is shot. Other features of the game included obstacles such as a cactus, and in later levels, pine trees and moving wagons, that can provide cover for the players and are destructible. The guns have limited ammunition, with each player limited to six bullets, and shots can ricochet off the top or bottom edges of the playfield, allowing for indirect hits to be used as a strategy. Western Gun was his next game licensed to Midway for release in the United States, with the title changed to Gun Fight for its American release. Midway's Gun Fight adaptation was itself notable for being the first video game to use a microprocessor. Nishikado's Western Gun allowed the two players to move around anywhere on the screen, whereas Midway's version Gun Fight restricts each player to their respective portions of the screen, with the characters made larger in size. Nishikado believed that his original version was more fun, but was impressed with the improved graphics and smoother animation of Midway's version. This led him to design microprocessors into his subsequent games. Gun Fight was a success in the arcades, selling 8,600 arcade cabinets in the United States, where it was the third highest-grossing arcade game of 1975 and the second highest-grossing arcade game
