The meteor strikes have caused great damage. We’ve gathered as much wreckage as possible so please use the salvage carefully. Complete the primary objective and build the planet that will preserve humanity. Expand your developments onto the Supermoon in case the meteorite hazards get out of hand. Planet Unknown is a polyomino tile-laying game that mixes tile-placement, engine-building, simultaneous play, and resource and rover management for a unique and competitive gameplay experience. Supermoon is the first expansion.
