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.
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.

gave some doctor guy explosive diarrhea till he died
polished and unique
Simple, smooth, fun. Looks great, handles well, and is quite addicting. All for $10? It's a steal

The game is eh. Too many items and too little space to put them means half your shops and item drops are, simply, pointless. A lot of enemies are absurd bullet sponges as well. I had a 1000-1250 DPS laser beam going near-constantly and stuff still lingered way too long. Also, aiming is miserable. EDIT: Okay turns out Bacteria just SUCKS and all of my problems come from playing it.
这个游戏呢我玩了38个小时从开服的时候没有发行购买的时候我就已在玩嗯玩法很舒服比较烧时间平均一买下来要半个小时或者是二十多分钟这样子但是呢这个游戏也是有点缺点的缺点就是玩法不足玩够十个小时或者是二十个小时以上的话基本上会觉得这个游戏会有点发腻
Ein definitives JA! Wer Rogue Lites mag und bock hat auf eine wenig Twinstickshooter der ist hier sehr gut aufgehoben.
What a game, Isaac but you are a virus... also I thought it will have bacteria music by DJ Toenail but really BANGER OST
Unexpectedly fun, and a great creative twist on the usual roguelike formula. Normally I hate bullet hell games, but this one is the exception. This is truly great.
Great game!
Solid Game. Seemed way too easy at first, and I almost Reverse Rick Astley'd it... BUT I'm Glad I didn't. The Difficulty and challenge ramps up quite a bit in farther levels, as does the fun. Different Pathogens have different mutation upgrades, so it gets even more interesting after unlocking some. Glad I stuck with it, good game!
