Defend the galaxy in Stellar Bastion, the ultimate adrenaline-fueled wave-survival shooter. As the final gunner standing on a besieged star-fortress flight deck, your mission is simple: survive the relentless onslaught of alien swarms. With your rifle firing automatically, your survival depends entirely on your tactical movement. Every 13 seconds, the waves intensify, pushing your reflexes to the limit, while every fifth wave unleashes a terrifying Hive King that accelerates the swarm into a chaotic frenzy. How many waves can you conquer before the bugs overwhelm your position? Master the battlefield by collecting powerful weapon drops, including heavy-duty shotguns, rocket launchers, and machine guns, while relying on your infinite MK-1 sidearm when ammo runs low. Level up mid-combat to select from 22 unique perk cards that evolve your playstyle without ever pausing the action. Best of all, Stellar Bastion is a 100% free online game that requires zero downloads or installs. Whether you are playing on a PC, Chromebook, or mobile device, you can jump straight into the fight instantly.
