Story and Quests

Key Features
- Dozens of Quests: Players continue their journey for survival by completing quests on behalf of the survivors of the Knox Incident.
- Expanding Play Area: Although only one location—Muldraugh—is explorable at the start of the game, the searchable area gradually expands as you progress through the main quest.
- Unfolding Story Through Quests: Uncover the truth behind the crisis and root it out by completing quests and talking to NPCs.
Time-Limited Raids

Airborne transmission
- Unlike in Vanilla Zomboid, the player is not an immune survivor who is resistant to airborne infection.
- Even if you cure the infection using the cure mod or similar methods, your character will become infected with the Knox virus again after a few days.
- Masks, gas masks, and oxygen respirators—none of these can protect the player from infection. The only way to escape this inevitable infection is to return to the bunker.
A Hideout for Players

- As players progress through the game, they can decorate their own living space.
- Use paint, brushes, and all kinds of furniture to decorate your hideout in style!
