Joust is an arcade game developed by Williams Electronics and released in 1982. While not the first game to feature two-player cooperative play, Joust was more successful than its predecessors and popularized the concept. The player uses a button and joystick to control a knight riding a flying ostrich. The object is to progress through levels by defeating groups of enemy knights riding buzzards.
Joust is a platforming game where the player controls a yellow knight riding a flying ostrich or stork, from a third-person perspective. Using the two-way directional joystick and the button for flapping the ostrich's wings, the player flies the knight amidst the floating rock platforms and above pools of lava; when maneuvering off the screen to either side, the player will continue its path reappearing from the opposite side. The rate at which the player repeatedly presses the button causes the ostrich to fly upward, hover, or slowly descend.
