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.

Great bullet hell rogue lite game with a great game loop, tons of customization options, and awesome music/visuals. The concept is quite unique, instead of your normal space ship you are a bacteria trying to destroy your human host. There are multiple types of bacteria for you to choose from, and then there are tons of "organs" which in this game are weapons/upgrades. Some upgrades are really powerful, especially combined with the right combination of bacteria "evolutions". However even with powerful "ship" and weapons you will still need to learn boss behavior, bullet patterns, when to dash/dodge, and other bullet hell shooter basics. Luck is an aspect of the game as some randomly drawn weapons/organs are a lot better than others, although the game can get pretty hard even if you are lucky. Fortunately like most rogue lites at the end of each game you get to gain something like experience which will permanently level up your bacteria. Since there are multiple types of bacterias, this means there are lots of replayablity/grinding. It's good that the game is fun enough you want to try to different combinations anyway. Last thing about the game, the music and sound effects are quite good. It makes each run more fun.

fun, but balncing is in the later stages way off. Lung/ heart is purely luck based. And theres to little variety in weapon/skill sets
Amazing depth, visuals pop, Game pace and variety is awesome! Sure wish it had a game save mode though, for when life gets in the way. Not having a multiple game save option makes this feel like it's setting up to be subscription based. Hope I'm wrong, won't deny the gameplay is brilliant.
Love rougelikes and this game really does feel different each game
really nice game
El mejor roguelite de microbios que he probado, no solo es entretenido si no que tambien tiene un muy buen arte y la musica es demasiado buena 20/10
super fun game. but man I hate the roguelike permadeath. very happy with it even despite the permadeath. so many fun builds and enemies stay fresh.
like the idea of evolution, and upgrading throut the gameplay. very cool concept with the bacteria. maybe not the same level as ISAAK but still tho
One of the greatest Rogue-Like games I ever played, the gameplay loop is perfect, the progression is great, and the way you unlock the brain is so complicated but is so much fun too! PLEASE play. (Also I love the theme of it, especially the codex, It's cool to read the codex and actually learn things about the immune system and other micro organisms.
Very cool rogue like. I really like the weapon placement system.
