Mortigen

Something escaped into the lab with you — and it grows stronger with every horde you survive. Forge weapons from the dead, rescue the dog, and outlast the outbreak.

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 roguelites, 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.

— COMBOS THAT BREAK THE GAME — Upgrades stack and react. Frost Plague turns your Wind Cannon into a wall of ice. Storm Serum makes every grenade electrify the whole blast zone. Run both and everything you hit freezes and shocks at once. Every elemental upgrade enhances every weapon — find the build that snaps a run wide open.

— THE STRANGER IS WATCHING — Something else escaped into the lab with you. At first it only watches. But every horde you survive, it heals, grows 15% stronger, and gets bolder — until it stops stalking and starts hunting. Kill it early, or pray you're ready when it comes for you.

— RESCUE THE DOG — Somewhere in the annex, a dog is waiting. Find it and it fights at your side. But the Crimson Heart changes what you are — and the dog will know.

— PROCEDURAL LABS, ESCALATING HORDES — Every run rebuilds the Mortigen annex into a fresh layout of corridors, rooms, secrets, and breakable equipment. Walkers, brutes, hunters, and lurkers unlock in waves. Spawn rates tighten. Boss encounters punctuate every horde — including the Dark Professor, your former superior, who still thinks, still plans, and still fires back.

— 15 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 — roguelike progression that carries forward even when a run ends.

— BUILT FOR REPLAY — • 11 enemy types, including 7 boss encounters with distinct AI • 23 trophies tied to persistent progression • An in-game encyclopedia of everything that's tried to kill you • Layered music that intensifies with every horde wave • One emergency revive per run — spend it or save it • Cosmetic outfits to earn as you survive

— DESIGNED FOR iPHONE AND iPAD — • Auto-targeting for true one-handed play • Gamepad, keyboard, and touch with automatic priority detection • Localized in 13 languages • Play offline — no account required, your progress stays on your device • Optional online leaderboard for run scores

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.
