Mod type: client-server.
Mod description: Allows you to set up biological contamination zones on the map. In the set area, the character needs a gas mask with a filter or a full set of chemical protection suit (how to configure), otherwise death from suffocation occurs (you can add getting a disease – biological contamination).
Contains:
▸ Deadly disease – biological contamination and treatment for it (antidote).
▸ Icons (being in the zone, disease icon).
The ability (via config) to disable the vanilla chemical zone and thereby combine the operation of the zone and vanilla particles of green smoke (works much more optimized than third-party fogs and smokes).
