Breach Hour: Alien Defense

The alien is awake. Your door is all that stands between you and it. Breach Hour is a sci-fi survival defense game set on a haunted space station. Race to claim a room, build turrets, traps and shields, upgrade your door — and hold on while a hunting alien grows stronger with every hit. Or flip the game around and become the alien yourself. 🚪 DEFEND YOUR ROOM • Claim a room before the alien wakes up • Build laser turrets, stasis traps, EMPs, force fields, coils, drones and more • Upgrade your door and your bed to earn more and hold out longer • Repair in time — every door has its breaking point 👽 8 DEADLY ALIENS, EACH HUNTS DIFFERENTLY • The Splitter bursts in two when you destroy it • The Phantom walks straight through doors • The Brood Mother never comes alone • The Juggernaut's armor shrugs off your turrets until it cracks • Plus the Crawler, Stalker, Lurker and Spitter Every alien levels up as it fights, flees to heal, and gets angrier the longer you survive. 🦑 PLAY AS THE ALIEN Take control of the hunter.
