Fortnite patch v4.3 has arrived and brought with it a ton of changes to the game, though you might not notice all of them right off the bat.

Most of the biggest changes to both of versions of Fortnite were several major bug fixes and a few nice improvements to systems like Turbo Building. Save the World also saw the return of the Blockbuster questline, with a few new missions and a ton of new Skill Points; the new Mythic Soldier Carbide hero; as well as some weapons that are brand new to the mode, like the Port-a-Fort and the new Tiger Assault Rifle.
