Fortnite Season 3 map leak has been immediately ruled out as a fake. It's obvious why the image was shared via social media so adamantly, as the main theory is a flood or body of water will cover the map. We've even seen a leaked image from Sony clearly showing the battle bus flying over land flooded by water.
Fortnite Season 3 Map Leak Ruled as Fake for Water Inaccuracies
You can see the mountain peaks out of the water which clearly makes sense, but the Sweaty Sands are somehow still above water. Fans were quickly to call out how this image shouldn't be considered real and is fake.
Players should understand it's highly unlikely the map is completely covered in water, as most don't want to swim around for most of it. Most likely, Epic Games is going to add new structures above the water to connect the body of water, and give players a place to fight.
