I died to the storm in the first game, not realizing how quickly it moves in this new mode, and how much faster it'll kill you than in the regular game.
Before I got to the safe zone, though, I saw someone had activated the Infinity Gauntlet and started wiping out other players (as seen above).
In my second game, I knocked off a couple of opponents early in the match, stayed out of the storm, and stayed safe as Thanos ripped my opponents to shreds from a distance. There's one bit of good news: Once the Gauntlet is claimed, Thanos will always appear on your map, so you'll know where you can (or can't) hide.
