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.

For 10 dollars? Take my money!!! You'll get way more out of this addictive game than some AAAs. Fun, addictive, challenging, cool game mechanics when you start to figure everything out.
Fun game. I do wish there was more flexibility in trying to create your perfect build, even if it was a different game mode that didn't unlock additional things.

It captures the first stage of Spore so well
This game got me addicted like nothing else... but minecraft.... everyone likes minecraft. But this game is something else, notonly the graphics that are very good and vibrant but also the gameplay that doesn't feel repetitive.... CAUSE IT ISN'T! Each run you do ends up being: 1: abosulte dogpoop 2: dies mid game 3: aboslute god of destruction and despair. Trust me, this game is worth the 13 bucks.
Incredibly fun and addicting. I tried to break the game, managed to do it and the game didn't crash. 10/10
