About

The game is a work in progress, and it is highly likely that you will encounter bugs.



Defend the Final Frontier. Breach Keeper is a cooperative sci-fi game where you and your crew hold the line against hordes pouring from dimensional portals. Collect rewards, arm up, fortify the ship, and see how long you can keep humanity’s last outpost standing.

Between waves, every second counts. Mine ores, stockpile resources, and push research to unlock buildings, abilities, and weapons, then upgrade them before the next breach opens. The better you prepare, the harder you hit when the swarm arrives.

Build without limits. Place and orient defense turrets exactly where you need them, gatling guns, flamethrowers, heavy cannons, and more. Upgrade them freely to unlock special abilities. Raise a Command Room to expand your construction options, and an Armory to grow your arsenal.

Organization is everything. Assign roles and cover every need of the base:
  • Scouts track resources and recover codexes for research;
  • Builders construct, upgrade, and repair;
  • Gunners reinforce the defenses with their arsenal;
  • Miners harvest resources and keep production running.

A coordinated crew holds longer than any lone hero.

Scouting is critical. Explore the map to reveal resource nodes and locate rare codexes, the key to unlocking capital buildings that harden your base’s defenses. Miss them, and your fortifications stay limited when the breach escalates.

Victory demands everything that came before. Ignore none of it. Only crews who master every role stand a chance against the common enemy. Hold the line, adapt under pressure, and earn survival the hard way.

How many waves will you survive ?
