Prices
The United States storefront in every case, so this compares stores and not countries.
Prices
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.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
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.

Reviews
There used to be a Flash game called Bubble Tanks back in the day that is shut down at this point. It was kind of rudimentary but it was so fun to build up a strong Tank over time and gather upgrades to keep exploring. This game scratches that exact itch while also being MUCH better in every category. The music is awesome, the gameplay loop is fun, and there's so much build variety! In Pathogenic you either adapt, or you die.

Incredibly fun and addicting. I tried to break the game, managed to do it and the game didn't crash. 10/10
Some will say a lot Some will say a Few But to the Makers I say Thank you.

doing biology in high school allowed me to understand a few words in this game.
Game is amazing
İsaacten sıkılan insanlar için bence iyi bir oyun. Oyunun evrimleşme mekaniği dışında diğer kalan her şey isaace benziyor. Sıkılmadan oynadım ama bence oyunun tek sorunu karakter sayısının az olması ve bazı karakterlerin sadece bir kaç şeyi değiştirmişler o kadar. Silahlara gelirsek sadece bir kaç silah kullanılabilir diğerleri ise o kadarda güçlü değil ama bence oyuna yeni güncellemeler veya dlcler getirerek bu durumu düzetebileceklerini düşünüyorum.
딱 로그라이크의 전형적인 플롯을 따르는 게임입니다 운이 좋으면 무슨짓을 해도 깨고, 운이 나쁘면 무슨짓을 해도 못깨게 되어 있습니다 무기나 버프를 얻을 수 있는 기회가 적어서 스테이지를 지나면서 역전을 할 수 있는 경우는 매우 드물고, 결국 처음부터 강한걸 얻어서 계속 강하게 만드는 선형적인 플레이만 하도록 강요됩니다 그래도 강해졌을때의 뽕맛이 엄청나서 할만한 게임이니 만원 정도의 가격이면 훌륭하다고 생각합니다 PC방 비유법 : 1000원당 1시간으로 치면 가성비 엄청남 매우 추천
Pathogenic has become one of my favourite games since discovering the demo, it's so fun to see the amount of combinations you can make.
