Archon

Archon: The Light and the Dark is a strategic board game with some similarities to chess. Two sides, a light one and a dark one, consisting of 18 pieces each compete on a board divided into (9 by 9) squares. You win the game by having one of your units on each of the five powerpoint squares, by removing all opposing pieces from the board or by imprisoning the last remaining creature of the opposing side. The Atari 5200 is a homebrew port from the 8-bit computer series and was never officially released on the Atari 5200 platform.
