Warp into a busy galaxy with nothing but your wits and a tiny ship. Explore sectors, mine asteroids, take on faction missions, sell resources and upgrade your loadout. Earn the respect of a faction to unlock new weapons and ships. Attack other ships and steal their resources but beware: factions won't tolerate hostility for long without retaliation. Masteroid is an atmospheric, 2D space game with procedurally-generated sectors and casual, relaxed gameplay.
