Recently, a modder with the nickname VelyXCore introduced a new version of a modification for Grand Theft Auto V that adds mechanics related to survival in conditions of radiation danger to the game.
He installed several zones with different levels of radiation on the map, for example, the "epicenter" was Humane Labs, and the Fort Zancudo base has a "high level of danger".
After entering such a zone, radiation begins to accumulate in the character's body: the closer to the source, the faster it happens. If nothing is done, the protagonist may experience organ failure and die. You can protect yourself with found gas masks. In the latest version of modification 1.5, a point was added where they can always be obtained.
The Exclusion Zone 1.5 mod is distributed via gta5-mods.
