You can defeat him and get a Vault keycard and you can also get his ability and use that ability against other players.He then mentions all the items that have now been unvaulted in the game:"The Pump Shotgun is back, The Tactical SMG is back, but you need to know that the Tac SMG is not as strong as it used to be. Boogie Bombs are back , Combat Shotguns are back, but I do think they've been nerfed. The Scoped Assault Rifle has also been changed."Don't get too hyped about these guns... The Pump and the Charge are still the better shotguns in my opinion. Shockwave Grenades are back btw, that is a huge W. He then goes on to describe the latest fishing features, including Thermal floppers:"We have Thermal Floppers now... there's Bounce Floppers, Normal Floppers and Jelly Floppers. Mentioning how the loot pool has changed, he also states that Bounce Pads are now back in the game.Here's a list of all that has been vaulted and unvaulted in Fortnite Chapter 2 Season 4:Vaulted:• Decoy• Flaregun • Hunting Rifle • Launch Pad• Pistols• Rapid Fire SMG• Stink Bomb• Submachine Gun • Tactical ShotgunUnvaulted:• Boogie Bomb• Bounce Pad• Combat Shotgun• LMG• Pump Shotgun• Revolver• Scoped AR• Shockwave• Tactical SMG— GunasamssYT - Fortnite Leaks & News (@Gunasamss_YT) August 27, 2020SypherPK ends the video by eking out a glorious, superpowered Victory Royale:"That is so cool... these abilities are insane!"These mythic abilities are CRAZY 😳 pic.twitter.com/198TZ8XHif— SypherPK (@SypherPK) August 27, 2020This season is a W so far.
