Ergon is a futuristic strategy game for 2 players. The playing area represents a new planet on which each player is trying to establish a colony, and the objective is to ensure that your colony survives by destroying your opponent's headquarters. You start the game with a headquarter and 3 units. New units can be built if you have sufficient energy and resources. Your headquarters produces 1 resource and 2 energy each turn, and installations can be built to produce more. At the beginning of the turn you will have up to 3 options. PASS is always available. USE UNIT is available as long as you have at least 1 unit. BUILD UNIT is available if you have an unoccupied factory (your headquarters counts as a factory) and enough energy and resources to build at least the cheapest unit. Once you select an option you will be asked to choose an appropriate unit or installation on the board.
