|Call of Pripyat|
The Gas Cloud anomaly resembles a Gas anomaly and causes chemical burns. The Gas Cloud however moves and deals far more damage. As such, it is the chemical counterpart of the Comet and Tesla anomaies.
Even while wearing one top-tier protective suit and some chemical-protection artifacts, only a touch of this anomaly would reduce health dramatically and a direct hit may result in instant death. Running through it is the best thing to do, as it will prevent the player from taking high damage. The antidote can severly reduce damage dealt by the Gas Cloud.
This anomaly also does not spawn any kind of artifact.
Call of PripyatEdit
There is only one of them in the entire game. It is floating above the Vine Anomaly in Pripyat. The player must get past it in order to reach one of the apartments to find a stash and an artifact.
