The Square is a Factorio challenge mod where your factory begins inside a tiny square and can only grow by researching Square expansion. Each square expansion level adds one buildable tile in each direction. The intended purpose of this mod is to constrain space and force efficient design of the factory. This mod is pre-alpha with much tuning and playtesting still needed. Only supports the vanilla game for now but Space Age support is planned in the future.
