Blast Zone



A blast zone is the resulting irradiated area in Fallout 76 created when a nuclear warhead makes an impact, identified as a red circle on the map.

Background
After completing Mission: Countdown in any of the three nuclear silos, sites Alpha, Bravo, or Charlie, Vault Dwellers can insert a nuclear keycard and enter the launch codes which grants access to the targeting computer. They can then target a location on a military-style version of the map to fire the missile and trigger Death from Above.

Before the nuclear missile is launched, a broadcast warning alerts the entire server that a nuclear strike is imminent and an air raid siren sounds. It will take three minutes for the bomb to drop and the created blast zone will last for two hours. Upon nuke impact, player characters and most workshop objects inside the blast radius will be destroyed instantly. Anyone inside of an interior cell within the blast radius will be safe from the effects.

Player characters outside the edge of the blast zone will not be killed. Once a player character has entered the zone, they will take severe radiation damage unless wearing power armor, a hazmat suit or Chinese stealth armor. NPCs inside of a blast zone will don hazmat suits as well.

Protected zone
While where a nuke is launched is dependent on the choice of the player character, certain portions of Appalachia are in a "protected zone" and cannot be targeted. The protected zone includes many areas of Appalachia where low-level player characters are likely to have early quests. If any part of the blast radius would be within the protected zone, the nuke cannot be launched.

Public events
If a nuke is launched at specific locations on the map, a public event with a high-level boss enemy will begin. The listed location only needs to be contained somewhere within in the entire blast zone radius and does not have to be explicitly targeted as the center of the blast zone.

Nuclear Winter
In Nuclear Winter, player characters must obtain four launch codes and a nuke briefcase before gaining the ability to drop a nuke. By activating the briefcase, a targeting computer allows the player to drop a nuke anywhere they choose.

Similar to Adventure mode, the blast radius will instantly kill any players inside at the time of impact and will leave a red radioactive circle for a duration. Unlike Adventure mode, the countdown timer is reduced to 20 seconds and the blast zone is comparatively smaller.
