Archon is loosely based after the game of chess, but with the added trait that pieces do not simply kill other pieces-when an individual piece attempts to kill an opposing player's piece, a battle screen ensues, and a fight occurs. Generally, but not always-stronger pieces are able to overcome weaker pieces. Fights can also result in double-kills, where each piece involved in the battle is killed.
Other additions to the game include special abilities held by certain pieces, as well as a Spellcaster piece, which acts as the leader of each side.
