Fog of War (formerly Sneaky Silencers) is a Limited Time Mode introduced during Season 2. Note that Beaumont treats fog of war as if it has an accepted definition… You can play the game alone or with your friends. Astral’s Fog of War is updated automatically, meaning there is nothing for you to manage or update as a GM. On December 28th, 2018, Sneaky Silencers returned on the 10th day of 14 Days of Fortnite, and returned again on August 13th, 2019.
