Knights of the Round is a side-scrolling beat-em-up released on SNES in 1991 that draws from Arthurian legend. The game follows a group of knights as they battle through medieval-themed stages in an action-focused adventure.
Recent coverage has focused on Wardens of Avalon, a spiritual successor that takes the Knights of the Round table concept in a new direction. Rather than a traditional beat-em-up, Wardens of Avalon operates as a top-down action RPG where players discover that King Arthur has corrupted the afterlife by drinking from the Holy Grail. The game challenges players to combat this corruption and restore their Citadel, blending the Arthurian setting with dungeon-building mechanics.
