Overview
Defend the last living planet from an endless swarm. Shoot enemies down and forge orbital defenses from their debris — merge three into one: turrets, lasers, shields, stations, up to legendary citadels and arks. The further you push, the stronger your next run starts: gems boost you permanently. Planet defense, merge and roguelite in one.
