"Can you use the fog cover to your advantage? The stage will be shrouded in fog through the battle. However, the density of the fog will change as the battle goes on!"

Quotes
"SRL Challenge Team here with info on the Foggy Notion Challenge! Contrary to its name, we know JUST what this Challenge will entail—a lo-vis showdown on stages blanketed in ever-changing fog. Do you exploit it for stealth or choose a fog-friendly loadout? We haven't the foggiest!

And let's clear the air about the Foggy Notion Challenge schedule, shall we? The first window will be from 7 PM to 9 PM PT on 6/27. Then from 3 AM to 5 AM PT on 6/28, and again from 11 AM to 1 PM PT the same day. Hope your schedule is clearer than the air on these stages!"
