Fortnite players discover a frustrating glitch with Captain America's shield ability, where, under circumstances, they'll be able to use the shield bash technique permanently. Following the mixed reception of last season, most fans were excited to see another new Marvel collaboration for Chapter 5 Season 4 of Fortnite. This time around, Dr. Doom is the primary threat as he seeks to gain total control over the island with the aid of the power stolen from Pandora's Box.
