$9.99Pathogenic Become the disease, build your parasite
You are the disease. Pathogenic is a fast roguelike shooter set inside a human body: hunt cells, rip out their organelles and graft them onto your own, building a parasite that breaks the game. Colorful, squishy and hard, with runs that end and immediately demand another.
Is Pathogenic worth it?
Pathogenic is worth it if…
- you want a roguelike where the build you assemble matters more than the gun you found
- you enjoy fast twin-stick shooters and bullet hell patterns that punish sloppy movement
- you like runs that end badly and still pull you straight into the next one
- you have a friend next to you and a controller to hand them
- you ever looked through a microscope and thought you could conquer that

Rip out organelles and build a monster
Every enemy you kill is spare parts. Tear organelles off defeated cells and graft them onto your own body: flagella to move, mitochondria for power, secretors for ranged attacks, spikes for melee. Where you attach them matters, because effects chain together and the right combination turns a humble cell into something the immune system has no answer for. Then evolution reshapes your body mid-run, changing your slots and your plans with it. The builds get strange and sometimes outright broken, and finding one is half the fun.
A war fought at microscopic scale
The host fights back. Immune cells like macrophages and T cells come after you, rival parasites such as tapeworms and protozoa compete for the same flesh, and bosses wait deep inside the organs. Everything is rendered in bright, saturated color over a soft-body physics simulation, so cells wobble, splat and burst in ways that feel alive rather than clinical. The soundtrack keeps pace with the carnage, and even without a drop of blood, micro-warfare lands with real weight. It is a bullet hell at heart: dense fire, quick reflexes, narrow escapes.
Infect a friend, locally
Co-op here means sharing a couch, not a lobby. Two parasites share one body's worth of chaos, weaving through bullet patterns and arguing over who gets the good mitochondria. The game is difficult solo, and a second player changes the math: more guns on one cell, more bodies to soak mistakes, and twice as many bad evolutionary decisions made with total confidence. Sessions run short, so it fits an evening of quick rounds between friends, each run a fresh layout in a fresh organ.
What should you know before playing?
How long is a run?
Short. Stages are compact and fights resolve quickly once your damage keeps up, so a full run fits in a modest sitting and a failed one ends sooner. That pace is the engine of the whole game: a run ends, you spend your plasmid fragments, adjust your upgrade tree, and start again with a different body and a different plan.
Does progress carry over between runs?
Yes. Between runs you spend plasmid fragments on a permanent upgrade tree, and each playable parasite has its own tree, so you can steer different organisms toward different playstyles. The trees are impactful without being mandatory, and you can reassign points freely as your plans change.
What makes it different from other roguelike shooters?
The setting and the body you build. Instead of collecting weapons, you graft biological parts onto your own cell, and their position and connections matter: a weapon near the front hits more reliably, a shield placed well blocks more shots, and evolution can rearrange everything mid-run. The whole thing plays out inside a human body, from the lungs to the heart to the brain, with a soft-body look that makes every kill feel squishy and satisfying.
