$9.99Pathogenic Become the disease, build your parasite
Build your parasites from looted organelles, stack absurd synergies, and blast through lungs, heart, and brain together in this fast, replayable twin-stick roguelike.
Is Pathogenic worth it?
Pathogenic is worth it if…
- you like co-op games where you and a friend break builds together
- you like fast twin-stick runs with lots of retries
- you like customizing a character part by part until it gets silly

Two parasites are worse than one
Pathogenic tags local co-op, and the roster backs it up with six playable organisms plus one extra made for co-op. You each run your own parasite with its own plasmid upgrade tree, so one of you can spec into flagella speed and spikes while the other piles on secretors and mitochondria for ranged damage.
Build-a-germ with questionable science
Every run starts you as a simple cell. You hunt macrophages, T cells, tapeworms, and protozoa, rip out their organelles, and graft them onto your own body. Flagella move you, mitochondria power you, secretors shoot, spikes stab. Placement and connections matter, and evolutions can reshape your cell and force a rethink. Chained effects turn a blob of spare parts into a bouncing-laser, virus-spawning problem the immune system did not plan for. The soft-body physics make every cell wobble in a satisfying, organic way.
A body tour with bad intentions
The map is a human host rendered as branching lungs, pulsating heart chambers, and a tangled neural network, all procedurally generated so runs stay fresh. Formidable bosses wait deep in the organs, and rooms can be as dangerous as the enemies in them. You ride fluid currents between fights, grab plasmid fragments, and spend them on permanent plasmid-tree upgrades between runs. The loop is quick: short encounters, small stages, constant choices, then death and another try with a slightly stronger starting germ.
Hard, fast, and built to replay
This is tagged difficult for a reason. Enemy health climbs sharply between zones, bullet density gets thick, and feast-or-famine luck can decide whether you melt rooms or chip away at them. The pace stays fast, with tight twin-stick controls, readable colorful visuals, and music that fits an intestine firefight better than expected.
Good to know before you infect someone?
How does co-op work?
Each of you controls your own organism, builds from looted organelles, and keeps a separate plasmid upgrade tree, including one organism added for co-op play.
What do you actually do run to run?
You clear procedurally generated organ biomes, kill immune cells and rival parasites, collect organelles and plasmid fragments, and evolve your cell shape. Death ends the run and returns you to permanent plasmid upgrades, so the next parasite starts a little stronger and a little stranger.
Is it hard?
Yes. Enemy scaling is steep, rooms get crowded, and some runs live or die on whether your organelles synergize. Tight controls, invincibility frames on dodge, and meta progression help, but bring co-op friends who find repeated failure funny rather than annoying.
