Los Justicieros (Zorton Brothers)1993

Sunset Riders is a side-scrolling run and gun video game developed and released by Konami in 1991. It is set in the American Old West, where the players take control of bounty hunters who are seeking the rewards offered for various criminals. Each bad guy has a big reward on his head, and they're helped by hordes of bandits, gunslingers, and horse thieves, so pack loads of lead.

Bandits are holding up a bank and have taken people hostage, and as a gunslinger, it's your job to shoot them. The bank has 12 doors, and the bandits are behind each one of them. When they pull a gun out at you when you open a door, you have only a few seconds to shoot them before they shoot you. If you shoot them too early (ie: before he sticks his gun out at you), it is considered unfair, and you won't score any points, but if you're too late, he'll shoot you and you lose one of your three lives.If you waste too much time, a bandit will come out from one of the doors and stick dynamite on it. You must then shoot the dynamite to get rid of it. If you're lucky, either a man or a woman will throw you a bag of gold coins. If you shoot any of these people by accident, you also lose a life. More often than not, the person will throw his/her hands up, saying "I haven't got anything". That's when they will be replaced by bandits. Some men will carry three to five pieces of gold on top of their heads, and shooting at all of the gold will award you with a bag of gold coins. Others will be tied up with rope. If you shoot the rope, there's more money for you, because not only will you receive one bag of gold coins, but you'll get three bags of gold coins.

Old west theme shoot-out. Using simple graphics, two cowboys one on the left and one on the right move up down, left and right trying to get a clear shot avoiding cactus at the other.

Express Raider was produced by Data East in 1986.

Western Gun, which served as an inspiration for Gun Fight in the USA (they're similar in gameplay and theme, but they're two different games), is a 1975 arcade shooter game designed by Tomohiro Nishikado, and released by Taito in Japan and Europe and by Midway Games in North America. It was the first video game to depict human-to-human combat, while the Midway version was also the first video game to use a microprocessor. Following its November 1975 release in North America, it went on to sell over 8,000 arcade cabinets in the United States. It was ported to the Bally Astrocade video game console as a built-in game in 1977 as well as several home computer platforms. The theme of the game involves two Old West cowboys armed with revolvers and squaring off in a duel. Whoever shoots the other cowboy first wins the duel. Unlike in a real-life duel, however, both cowboys get numerous opportunities to duel in order to score points (one point per successful draw).

A shooting game, with a western motif. The player uses a gun (mounted to the cabinet) to escort the sheriff through a variety of dangers, gathering bounty for capturing criminals.

Released in 1989 on Sega Master System/Mark III, by Sanritsu.

Outlaw is a single-player arcade game by Atari Inc., originally released in 1976. It simulates an Old West fast draw duel between the player and the computer. Outlaw was a response to Gun Fight, released by Midway in North America the year before.
