Archon for Q3:A, or simply ARQ, is an interesting mod for Quake III Arena, inspired by an old game called "Archon". It is similar to a chess game (main game screen is a chessboard), but when two characters get on the same square, they are transferred to a Quake 3 Arena/OpenArena map (you select a map before beginning the game) and the two fight until one of them dies, conquering the square. Characters are divided into "light" and "dark" sides, that alternate movement on the chessboard. Objective is to destroy all enemy pieces.
