Shape Your Place Among the Stars
Asterium is a multiplayer space sandbox where you command a fleet and carve out your own place in a living galaxy.
Explore star systems, discover new worlds, take on quests, trade resources, upgrade your fleet, and fight in real-time 3D space battles. Start small and grow your influence through exploration, commerce, diplomacy, or force.
Command Your Fleet
Build and customize a fleet suited to the way you want to play. Lead your ships directly into real-time 3D battles, where positioning, fleet composition, equipment, and tactics determine the outcome.
A Galaxy Without a Script
Asterium is built around an open-ended sandbox rather than a fixed story. Different races, factions, empires, and players coexist within a galaxy shaped by their actions.
Trade with your neighbors, form alliances, compete for territory, explore the unknown, or wage war. There is no single path through the galaxy — what you become is up to you.
Build a Stellar Empire
Colonize worlds and develop settlements across the galaxy. Manage resources, expand your territory, and shape your empire as it grows from a handful of colonies into an interstellar power.
A Shared Galactic Sandbox
The galaxy is shared with up to 5 players. Cooperate, compete, trade, negotiate, and fight as player ambitions collide with the wider simulation.
Whether you become an explorer, merchant, fleet commander, colonial power, or something in between, Asterium gives you the systems to create your own story among the stars.
