About This Game

Defend the Portal. Survive the Swarm.

Humanity’s last gateways are collapsing.

Fight against relentless alien hordes as you defend massive interdimensional portals across hostile worlds in this fast-paced sci-fi top-down survival shooter.

In Lost Galaxy: Survivors, survival alone is not enough. Every run is a desperate battle to protect the portal from overwhelming enemy swarms while building devastating loadouts, adapting your strategy, and holding the line against impossible odds.

If the portal falls, everything is lost.

Fight through escalating waves of enemies, elite monsters, and massive swarms while defending the core of the battlefield. Position yourself carefully, manage enemy pressure, and survive as the chaos intensifies every minute.

Each world becomes a desperate last stand.
