The lab went dark. The infected are still moving. You're the last one in.
You are Dr. Luisen — biochemist, sole survivor of Mortigen Biopharma, and the only person left who knows what the company released. The doors are sealed. Your old boss is hunting you. And every weapon you carry was built from the things trying to kill you.
Mortigen is a top-down auto-fire survival shooter where you move, the guns fire, and every run is decided by the upgrades you pick before the next horde hits. If you love survivors-likes, bullet heaven runs, and zombie-apocalypse shooters, this one is built for you.
— AUTO-FIRE COMBAT —
Focus on movement and positioning. Your weapons lock on and fire on their own. One thumb is enough to play, but mastering the spacing is what keeps you alive.
— FORGE WEAPONS FROM THE DEAD —
Bile, marrow, bone, nerve tissue, and volatile serum residues become field-grade weapons: chain lightning that arcs through crowds, piercing rounds that punch through lines, plague grenades aimed at the thickest cluster, and a damage aura that melts anything too close.
— PROCEDURAL LABS, ESCALATING HORDES —
Every run rebuilds the Mortigen annex into a fresh layout of corridors, rooms, and breakable equipment. Walkers, brutes, hunters, and lurkers unlock in waves. Spawn rates tighten. Boss encounters punctuate every horde, and the Dark Professor — your former superior — still thinks, still plans, and still fires back.
— 14 UPGRADES ACROSS 4 RARITY TIERS —
From Bile Rounds and Frost Plague to the Corpse Crusher vehicle. Rare and legendary upgrades unlock as you hit trophy milestones across runs, so progression carries forward even when a run ends.

WHAT PLAYERS GET
A fast-loading, single-player survival shooter you can pick up for one run or lose an hour to. Clean controls. Real tension. A story worth finishing.
The annex is sealed. The truth is inside. So are you.
