Way over in the big void of space live some aliens. They coveted [your planet] and would do anything to live there themselves. So what's [your planet] to do? Yeah, blast through them all! Face off against waves of enemies, bosses, big laser planets, blackholes, wormholes, giant lasers, planets and asteroids across 7 game modes! Really Big Sky is a super fast, twin analogue shooter for the modern age! Everything is procedurally generated from the way YOU play the game, from attack patterns, strength of bosses and enemies, pacing between waves, generosity of bonuses... etc!
