Toxic Air

The air outside turns toxic. Players caught in the open report inhaling gas, which makes this a shelter round rather than a damage race — indoors is the whole answer.

The banner says“What if the air turns toxic?”
Hazard typeBiological
Where it hitsAny map, outdoors
How to surviveGet indoors and stay indoors. Unlike the wind and water scenarios there is no partial answer: being outside at any point in the round is the damage.

How the round plays out

  1. 1.The air turns toxic outside — the first sign is damage in the open rather than a visible hazard.
  2. 2.Anyone still outdoors keeps taking it, so a short trip becomes a losing trade.
  3. 3.The round stays that way to the end — cover does not expire, unlike a tornado or a rising tide.

Where it kills you: Any outdoor space, including rooftops and streets. Players die trying to move to a better building after the air has already turned.

What to do in the 30-second head start

  • ›Pick a building and commit before the banner — this is a sun-disappears round with a different cause.
  • ›Do not plan a route that needs street time later in the round.
  • ›Treat a car as outdoor space, because it is.

If you are already caught out: Get into the nearest interior, even a poor one. Once inside, stay there rather than trading up for a better building.

Worst maps for it: Maps with few interiors — the Golden Gate crossing has the least indoor space of the recorded maps.

Surviving is half preparation and half knowing the map — see the map list and the round guide for the 30-second head start.
