Warp into a busy galaxy with nothing but your wits and a tiny ship. Explore sectors, mine asteroids, sell resources and upgrade your loadout. Attack other ships and steal their resources but beware: factions won't tolerate hostility for long without retaliation.

Masteroid is a stylized space sandbox game built by a one-person indie developer. Masteroid is in active development (see latest features below) with new updates approximately monthly. Purchasing the game gives you access to all future updates on Itch.io for free!
