Archon is an NES video game and a remake of Archon: The Light and the Dark, which was never released on a Nintendo console. In Archon, you take control of either the light side or the dark side and battle the opposing force. It is similar to a board game. Once the player moves his piece onto another, the two will battle each other for the claim of the spot.
The game's board consists of a 9x9 grid, with each side being placed on the opposite sides of the board. The player's turn is determined by the bar at the top - blue implies dark and yellow implies light.
The following are the units in the game, separated by which sides they represent. A unit is either ground based, air based, or is a teleporter. The number of pieces of each unit implies how many of that unit you'll start out with, while the number of spaces implies how many spaces it can move during each turn.
