| New Patch: Balancing Adjustments | 2026-08-07 | Hi Parasites!We're back with a new update! This time the focus is mostly on balancing. We've been combing through all your feedback here on Steam and on our Discord reporting channels, and we noticed a few organelles and mutations performing far better than intended due to how the buffs were stacked. This patch will turn them down a notch, while also buffing several other organelles to encourage more varied approaches to infecting the human body.At the same time, there are several adjustments to the hp of enemies in the Heart, as we hope to make this "final" level more fitting to its status.See below for the full changelog:Organelle BalanceBu |

| Post-Launch Update: Addressing Player Feedback | 2026-07-22 | Hey Parasites!Pathogenic just passed 100k copies sold! Thank you so much for your support that helped us reach this massive milestone in less than a week after launch.

While it will remain as a harder late-game level, we have adjusted some of the enemies to make them less unpredictable. Dash attacks are now more telegraphed for the pathogens to evade, and the alveolar macrophages are receiving fewer buffs from their T-cells support.Traits also r |

| Pathogenic Demo Will Go Offline on Jul 14 | 2026-07-01 | A heads-up to all our fellow parasites: the Pathogenic demo will be taken offline on July 14th 15:00 UTC, exactly two days before launch.We’ve contemplated this decision for a while. Seeing everyone enjoying the demo so much and sharing all the crazy builds has been a big part of our motivation to keep working on the game, and we will dearly miss all the ridiculous combos from your pathogens (until the full game comes out, at least). Unfortunately, as a small dev team of two, we simply don’t have the capacity to maintain the demo while working on the full game.You might have noticed the demo has received multiple updates since Next Fest start |

Invade the human body with the shapeless Amoeba, experiment with new organelles, and more!New Pathogen: AmoebaThe Amoeba is our latest playable pathogen in the demo. Unlike other parasites, it has no defining shape – literally just start out as a tiny blob of 3 organelle slots. While this gives the Amoeba a tougher start (tip: get stash slot upgrades for extra organelles), players will be able to add new organelle slots as the Amoeba levels up.This means the Amoeba can grow into unique shapes to suit your specific builds. There are some restrictions in place to make sure it doesn’t bre |

| May Dev Blog: Working on the Heart and Lungs | 2026-05-14 | Hey Parasites!

Adaptive Immune SystemWith your parasite leaving multiple ravaged organs in its wake, the Adaptive Immune System is activated to send out more specialised immune cells against the invading pathogen. Helper T-Cells, B-Cells and Dendritic Cells now appear in the Liver level (and in the full game, later levels as well) as the human body attempts put an end to your adventure.Helper T-CellsLike their real-life counterparts, the Helper Ts activate and buff other immune cells to combat infection.
