ProtoGalaxy

ProtoGalaxy is an adventure in which you lead humanity’s fleet against a powerful alien race seeking to enslave the galaxy. You fight the invaders, explore the unknown and rebuild a home for survivors while the aliens pursue you.

Explore and create

Up to four players can team up to explore the galaxy, take on action challenges and solve puzzles. Ship parts let you customize your vessel, and physics can help you solve puzzles or defeat enemies. You can also create galaxies with the built-in editor and download galaxies made by other players.

Choose from a selection of turrets, reposition them at any time to deal extra damage and take down huge bosses. The map also includes leaderboards for high scores and eight achievements.
