The United States storefront in every case, so this compares stores and not countries.

Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 24.71/day in the week to Aug 31 → 25.86/day in the week after.
Too few observations to say whether a discount moves this store's chart at all: across the last 30 days Steam · Top Sellers · Poland has just 18 day-to-day chart moves that followed a price cut, against 2,498 that did not. We are publishing the count instead of a direction — 20 is the fewest we will draw a conclusion from, and price collection outside the United States began on 6 August 2026.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
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 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. Create powerful, game-breaking builds and become the ultimate pathogen.

Loot, graft, and assemble your parasite from dozens of unique organelles. Combine flagella 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 vector.

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.

Collect plasmid fragments to permanently upgrade your parasite's plasmid tree between runs. Each parasite will have it's own upgrade tree allowing for a range of builds to suit your preferred playstyle.

Navigate the procedurally generated organic landscape of the human body. Travel through distinct biomes like the branching pathways of the lungs, the pulsating chambers of the heart, and the complex neural network of the brain.
Our detailed, colorful world is powered by a soft-body physics simulation, giving every cell, enemy, and projectile a uniquely satisfying organic feel. The combination of hand-crafted design and procedural generation ensures endless variety - each run offers a fresh and challenging gameplay experience.

gioco incredibile, super vario, super adrenalinico, dopamina al massimo, prima volta che provo un rogue like dato che non sono il mio genere ma ci ho gia fatto 40 ore e ne farò molte altre, spero in futuri update con nuove classi e nuovi organelli, un complimenti agli sviluppatori per l'idea
De los juegos mas inmersivos que he probado, el hecho de que cada partida es totalmente diferente, hace que aburrirse sea complicado. El arte de sus diseños y la música implementada hace única a esta entrega, me da la sensación de algún juego retro con gráficos muy coloridos y vivos. La temática de microorganismos evolucionando sin duda es lo que mas me atrapó, algunos nombres en las mejoras tienen un trasfondo químico o fisico y sin duda es un detallado. Únicamente deseo que estés juego sea mas conocido y jugado, este tipo de entregas son las que valen un espacio en nuestra biblioteca

Fantastico gioco, rigiocabilità altissima e divertente allo stato puro, una dipendenza vera e propria!!
Basically Isaac with a fresh techno-coat of paint, and I mean that in the best possible way. Great weapon synergies, fast action, hidden rooms, vast unlocks, surprise rooms, 'skill-trees', and a pretty great soundtrack. One of the best of this genre. Highly addicting.
tres bin roguelite avec un potentiel enorme
lovely roguelike on par with isaac for me! i cant wait for more updates/content!
infinitely replayable and lots of different variations for builds. Extremely fun game for an exceptionally fair price. If you like BOI or other games like that, this is a must buy.
SLICK
fun
I didn't think this genre of game could pull me back in anymore, but here we are. In real life, the human body is an incredible thing. You're full of tiny micro-organisms in the forrm of an army ready to fend off intruders, and honestly? I feel it in this game. It's TOUGH, but it's so rewarding. The outer-run progression allows you to apply further mutations to your Invader, either unlocking new weapons or equipment that you can start with, or giving you a currency which you can spend upgrading your stats in your skill tree. Challenging, fun, great theme No notes, I just want more of it.
