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 · Poland over the last 30 days: the 21 chart moves that followed a price cut of more than 20% went a median of 12 places towards #1, and the 2,501 moves with no price cut behind them went 1 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.

Great fun - you can customize your upgrades on the fly and try out different interactions mid-game. Enemy variety is great so far, and there seems to be enough unlocks and modifiers to make it well-worth replaying over and over again.
爽玩 我还以为要干到大脑去呢 结果闪白是通关啊
[h2]LGN 85 | 重生之我在人体当蛊王 - 十分有趣的游戏框架,但也存在一些问题急需改进优化 [/h2] [i]“我不知道比起好评制作组是否更关注差评,选择这样评价只是为了自己的意见能被看到。”[/i] [hr][/hr] 《Pathogenic》是一款十分传统的 “以撒like” 横版弹幕射击游戏,同时融入了《SPORE》的进化和编辑玩法,有着高自由度的玩法和颇具挑战性的游戏难度。故事背景设定在人体器官内,作为一个不断进化的病原体对抗免疫细胞、病菌和寄生虫,最终杀死你的宿主。 我很喜欢这款游戏的表现效果。大多数敌人都采用真实病原体和免疫细胞作为原型,形象生动有趣,富有教育意义。例如B细胞产生的特异性抗体有追踪效果,辅助T细胞会抓住其他细胞使其狂暴等。游戏提供了七种不同的可操作"角色",每一个都拥有不同的特性和进化树。作为一款射击游戏,游戏的基本操控打磨得很好,不同细胞有着不同的物理特性,UI交互十分丝滑,足以看出制作组在优化操作体验上付出的心血。 然而随着游戏难度提高,一个致命的缺点也暴露无遗:作为肉鸽构筑游戏,装备刷新的随机性太强,数值强度差距过大,有时候抽不到好的武器和基因就只能从头牢到尾。特别是在高抗生素等级下,过于陡峭的难度曲线迫使你只能选择那几条最稳妥的配装思路。如果你打不过心脏,你缺的并不是技术,而是胞吐腔室蓄力轻松秒boss,代谢线粒体左脚踩右脚无限产资源,糖原漏斗强行解放耐力限制,精炼器利滚利全身换神装。 尽管如此,我仍然愿意肯定《Pathogenic》是一款物有所值的游戏,也更希望看到它在后续的更新中能对以下意见做出改进: [list] [*]优化数值机制,在尽量不削弱装备的前提下加强一些表现较弱,拿取率较低的武器; [*]添加更多reroll功能,在选择突变和boss挑战时能有更高的自由度,例如局外提供重掷次数和排除选项; [*]装备升级全靠运气,商店应该固定刷新一个升级模块或已有的细胞器; [*]血管献祭最大血上限,如果全拿就没有任何惩罚效果,不如改成直接扣血; [*]前缀词条除了增大构筑难度外没有任何意义,但凡设置成打折一半否则没有任何想拿的欲望; [*]不同病原体的局外成长和解锁项都是相互独立的!这些需要重复劳作解锁的东西理应被取消掉; [*]游戏画面的饱和度太高,长时间游玩十分伤眼,希望能在设置里调整画面表现。 [/list] A good game worth trying. 希望看到制作组的更多进步!
The build variety in this game is absolutely insane, and for this price, this game should be played by everybody. I don't even like bullet hells and this game still feels super fun. That said, I am only leaving a negative review in the hopes the developer sees this because this feature is unacceptable and irritating. When you click save and go to desktop, it doesn't do it, and instead changes the option to "do you REALLY want to save and go to desktop." forcing you to have to double select the option before it actually exits out of the game. This ♥♥♥♥ is annoying af.
