About Pathogenic Demo

CELLULAR COMBAT EVOLVED

In Pathogenic, you are the disease. Experience a visceral 2D roguelike twin-stick shooter where you play as a lone parasite fighting a desperate war against the immune system. Your goal is simple: infect and completely conquer your human host.

To survive, you must adapt. Hunt down enemy cells, rip out their organelles, and graft them onto your own body. Evolve from a simple cell into a complex engine of destruction, creating powerful, game-breaking builds to become the ultimate pathogen.

CREATE YOUR OWN PATHOGEN

Loot, graft, and assemble your parasite from dozens of unique organelles. Combine lashes for movement, mitochondria for power, secretors for ranged attacks, and spikes for melee combat. Chain organelle effects and discover powerful synergies to build an unstoppable disease.

FIGHT THE IMMUNE SYSTEM

Battle a diverse roster of enemies, from basic immune cells like macrophages and T-cells to rival parasites such as tapeworms or protozoa. Formidable bosses are lurking deep within the host's organs.

Common questions

Is it really free?

Yes. Pathogenic Demo is free right now on Steam, with nothing to pay.

Is this the full game?

No. A demo is a portion of Pathogenic Demo — usually the opening section — published so you can try it. It is free permanently, but it is not the complete game.

Where do I claim it?

On the official Steam page. We link straight there — we never host game files or act as a middleman.
