Astra Dominion is a free, browser-based, real-time space strategy game that brings thousands of players together in a shared universe. Players develop an empire, build fleets, defend colonies and compete for influence across the galaxy, accessing the game directly through a web browser. Its strategic themes extend beyond military expansion: recent updates highlight research balance, mining routes, resource production, transport and logistics, as well as missions and alliances.

These evolving features and galactic events give players new opportunities to plan, cooperate and strengthen their position. The website serves as a hub for both new and established players, with account registration and login alongside game rules, screenshots and news about updates and events. It also publishes player-related information, including a banned-player list and a hall of fame, and provides a way to contact the administration.

With its persistent shared universe and focus on empire-building, fleet management and competition, Astra Dominion offers a space strategy experience designed for multiplayer play
