Shoot-Out is based on the 1977 arcade game Boot Hill. It's a bit simpler than the arcade original in that there is no wagon that moves up the screen to block shots, but it does have scattered cactuses (that are destructible if you shoot them enough) and 4 way player movement (left / right movement is limited). This is a 2 human player only game (thus requiring 2 joysticks) with minimal sound effects. The game ends once 1 player has hit their opponent 10 times.
