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.

One of the best games I have played in 2 decades. It has everything. Requires skill and thinking but not ninja level particle physicists... everything about it from the game play to the music screams pure video-game joy. Worth every cent.
Describing Pathogenic as being like Hades or Binding of Isaac does neither of the games justice. Pathogenic doesn't have the personality or charm of those games, but the playability and polish are fantastic enough to put it in the top tier of rogue-likes and stick shooters. An easy recommendation given the price and satisfying amount of content.

its such a one of the best game i have ever played
Игра затянула своим разнообразием мобов, оружий, видов и впринципе визуально понравилась, думал что рогалик на пару раз но мне дико понравилось в него играть(люблю рогалики), вообщем как игру на поиграть и покайфовать рекомендую, любителям рогаликов особенно понравится разнообразие)
Awesome concept, great progression, huge replayability
good game enjoying it so far
Best twin stick shooter with a little bit of Spore mixed in.
Bastante buen juego, es educativo si leemos la codex y es bastante dificil 10 de 10
It's a fun, imaginative, and immersive game. Definitely worth the money. If you are thinking about buying it, you should! However, the progression feels arbitrary. You are not able to start a random run and actually win without having put in hundreds of hours beforehand to unlock various powers. This got frustrating when I had an amazing run, but arbitrarily lost at lungs because I haven't unlocked much yet. This also happened when I reached liver. Also, nothing at all is explained. I have kind of picked up what stuff is through playing it, but I still am super far off from understanding what an 'optimal build' would be, because the mechanics just aren't explained. Maybe the mechanics could be shown more through immersive means, but googling everything like in binding of issac gets old. I am excited to continue playing though.
Super fun game. The different pathogens, weapons and boosters are great. The movement dynamics are interesting, similar to zero gravity, since you are in a free flowing fluid. The weapons combination with the boosters is extensive. As far as boosters go, we're not talking about mods. That community is a whole other discussion. There are some wild ones out there. The game is definitely worth the money.
