[ NO MULTIPLAYER] [This mod is working on build 42.16, but i recommend this patch [url=https://steamcommunity.com/sharedfiles/filedetails/?id=3695724398]https://steamcommunity.com/sharedfiles/filedetails/?id=3695724398[/url] since i am reworking it completely. play that instead for now]
If you’ve ever unleashed the Necroa Virus in Plague Inc. and watched the world fall into chaos… now it’s time to survive it.
This mod brings the terrifying essence of the Necroa Virus into Project Zomboid, transforming the Knox Event into something far more hardcore. The zombies are no longer static — they evolve, becoming more aggressive, smarter (and sometimes even special) over time. These changes are fully modeled in-game, meaning the differences aren’t just in their stats, but also in their appearance and behavior.
Inspired by the iconic plague from Plague Inc., this version introduces expanded virus mechanics and increasingly aggressive undead systems designed to amplify tension, unpredictability, and dread. Expect brutal survivability, harsher consequences for your mistakes, and the constant feeling that the infection is always one step ahead of you.
[Be Advised]
This mod is not beginner-friendly by any means.
While playing, you might even feel a bit of 2020 nostalgia — you won’t be able to touch everything bare-handed without consequences. Masks matters. The airborne infection is fully modeled here, and you are not a special survivor immune to the airborne strain of the virus (you can disable this mechanic by turning the Air Infection option off in the settings).
Although the zombies may not seem too difficult at the beginning of the game, they will become a serious threat by mid to late game. They will no longer be a simple obstacle — they will be a constant danger. Barricade your doors and windows, because it truly makes a difference in this mod.
This mod was fully reviewed and tested on Build 42.13. Build 42.14 has just been released and has not been fully tested yet, so please expect potential bugs.
[Considerations]
This mod uses code from inactive/dead mods such as Sense of Smell and Susceptible. I was unable to contact the original creators to request permission. If you are the owner of one of those mods and do not want your code used here, please contact me so I can update this mod and recreate those mechanics from scratch. My apologies in advance.
Special thanks to Phil J Herman, Spyjack, Notloc, Mr Sunshine — and the biggest of them all, SimKDT. You’re the GOAT.
This mod took me 8 months to create, and I built it with passion and care.
