A turn-based 4X wargame for up to 100 players. The game world is made up out of sectors on a hexagonal grid with a designation (agricultural, industrial, etc.) The player must take control of them to receive resources which in turn (after processing) are used to produce new army units of various types. A civilian and slave population is employed to produce and manufacture goods. A technology level determines the type of units can be produced. Issued commands are processed for all players at a given interval, typically once a day. in Blitz games updates are more frequent (e.g. 10 minutes). The game was expanded on by various authors to include more unit types.
