Holon

Holon is a factory building game in which a whole production line can be turned into a single building and used inside another factory. Players extract shapes from the world and carry them along conveyors to the Hub. Each completed order unlocks new tools and requires more demanding shapes to be produced, so output must also be scaled up once the correct shape can be made.

Processing machinery is housed in Nests, small factories that the player can enter and build in. Inputs and outputs are connected, and machines are arranged to stack, rotate, cut, and paint shapes. From outside, a Nest operates as one part of a larger production line. Working designs can be saved and reused. Larger Nests can be unlocked, and smaller Nests can be placed inside them, so that familiar designs are combined into more capable factories with layers of machinery beneath a compact surface building.

The map is endless. Players can expand outwards to reach new resources, or build deeper to fit more production into the space they already have. Energizer towers connect productive areas and boost the machinery, and relays extend that boost to distant resource patches. The game has no combat and no deadlines.
