Knights of the Round is an arcade game released by Capcom in 1991. A side-scrolling beat 'em up based loosely on the legend of King Arthur and the Knights of the Round Table, the game features an role-playing video game-like level advancement system, with fighters getting new weapons and armour as they advance through the game, however the player can not choose how to upgrade his/her character - the level up system is static.
