About this game

The developer's description, from the game's Steam store page.

Quasimorph is a unique high-stakes roguelike that blends cyberpunk, cosmic body horror, and PMCs trying to profit from the Apocalypse.

Complete corporate contracts, and you keep everything you managed to extract, making your PMC stronger with every successful mission. Die, and you lose everything you brought with you. But you can always print a new mercenary and try the contract again.

Become the Boss of a Space PMC

Take on contracts from powerful corporations. Earn reputation through sweat and blood.

Turn your mercenaries into augmented weapons with cybernetic implants and body modifications. Explore planetary bases, secret laboratories, and the wreckage of starships. Recover new technologies and resources to upgrade your flagship.

In the distant future, space has been privatized.

Corporations are stretching their claws far beyond the Solar System. And something terrible is drawing near. Discover what unforgivable things humanity has done in the depths of space.

No one cares about the fate of a clone.

Didn’t make it? Rethink your approach. There’s huge room for experimentation: hundreds of weapons and armor pieces, unique gadgets, a deep augmentation and body modification system, dozens of classes, and unique mercenaries.

Adapt or Die

Corporations hire ruthless mercenaries to carry out their shadow operations. Demons twist human nature and corrupt the course of human evolution. Assemble a team of professionals, count your bullets, maintain your gear, and prepare yourself for every grotesque turn of this bloody slaughter.
