Minus Nine

Minus Nine is a top-down isometric survival shooter set in a top-secret underground facility on floor B9. After developing a vaccine for the zombie virus, you must protect it from the infected and reach a rescue helicopter on the surface. The game combines classic arcade action with roguelite systems.

Escape the facility

Your journey begins on floor -9F. The facility layout and enemy spawns change with each run, creating a shifting labyrinth. In the dark, you search for hidden Generators and plan your route; restoring full power unlocks the elevator gates to the next floor.

Fight and upgrade

Ammo and health are scarce as you battle zombie hordes. You extract Bio-Samples from enemies and spend them at the Rest Area, the elevator between floors, to improve four stats: Damage, Health, Ammo Capacity and Speed. Combat calls for precise aiming and positioning, while dynamic line-of-sight mechanics shape what you can see in the dark underground environments.

Death and rebirth

If the infected kill you, you lose your gear and wake up back on floor -9F. Your skills and experience carry the attempt forward as you try to escape again.
