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 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 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.

Игра интересная. Разнообразия хватает. На данный момент по 2 варианта босса на уровень. Новые предметы открываются по ходу игры (выполнению условий для открытия). Разные персонажи (клетки), есть клетка для игры на двоих (можно и одному играть). Примерно за 40-60 часов можно все открыть и попробовать (наверное и больше)
This game was made for me. I love it. I find it hilarious how accurate enemy designs are to a biological counterpart in real life. The gameplay is fast and arcade-y, the rogue-lite elements are fun and engaging. Many styles of play are represented, lots to discover, and a fun loop. I like playing a run or two randomly here and there. Very easy game to just pick up and play whenever.

Very well made and fun roguelike. Also for some reason the music in this game is godly. 10/10

Great twin stick shooter with roguelite metaprogression. Cool concept for a game as well.
目前玩了十五个小时就通关了两次心脏,未更改难度。游戏推荐指数三颗半星。先说优点:1.较为新颖有趣的题材和质感2.建立在病毒入侵人体的基础上的剧情展开也挺有意思的(过场真人小动画实属难绷)3.游玩体验较好有不少玩法可以尝试4.主题病毒的各种变形十分有趣,需要根据不同形态的细胞器分布来合理规划选择的武器,这点算是不错的创新。尤其是变形虫的设计,可以自己一点点通过进化捏出想要的形态,设计的很有意思,值得尝试。接下来是缺点:1.局外养成成本过于高。花费了约五个小时玩变形虫,但是最终的解锁结果才约到1/3,并且几乎没办法打得过心脏关。我认为花费太多时间玩同一个细胞体并且没办法通关的情况下会降低游玩兴趣。2,难度曲线不平滑或者说敌人强度上升太快了。明显感觉到从一个器官到下一个器官的敌人强度上升很大很大,相比之下自己的提升很小,未免有些太难了(ps:玩死亡细胞的时候都没感觉这么难)。3.局内养成太过于随机,难以构建想要的流派。商店一关就一个,刷新商店要花的钱很多很多,不刷新的话又没办法升级已有细胞器也难以找到想要的细胞器就几乎没有强度提升,玩的就会很难受。4.武器强度差距大。主要涉及到低射速高伤害和低伤害高射速的问题,前者相比于后者没看出任何的优势,感觉数值设计不大合理。总结:总的来说是一款很值得尝试的游戏,虽有缺点但是仍有机会进行更新完善。
SOUND TRACK IS AMAZING BRO. THE GAME IS AMAZING.
Biology-themed rougelike with a wide variety of builds, incredible soundtrack and fun, frenetic gameplay. Well worth the asking price!
This game is absolutely excellent. Great music, great visuals, great gameplay. Remote Play co-op is smooth and delightful, and leads to great banter and strategizing. There has not been a game in quite a while that has effortlessly held my attention for over 9 hours on the first play session. I highly recommend Pathogenic.
