3) Lock on Pistol aka Smart Pistol
Lock on Pistol, commonly known as the Smart Pistol, is a specialized weapon that locks onto and tracks targets in combat. According to the information, this weapon is ideal for taking on targets in high-speed chases. It will be useful for spotting opponents from fleeing.

5) Tabor Hill's Locker
One of Fortnite's oldest and most family-friendly content creators, Tabor Hill, is finally getting his own Locker in Fortnite Chapter 4 Season 2. Once the Item Shop rotates, an assortment of cosmetic items will be available for purchase as part of the Bundle offer.
6) Hiss Clique Quest Pack
Although it was speculated that the Hiss Clique Quest Pack would be an Xbox exclusive, it has now been confirmed that it will be available for players on all devices. It a Quest Pack and will provide players with 1,000 V-Bucks after they complete the Challenges associated with it. It will likely be added to the Item Shop once the downtime ends.
7) New Skins/Outfits
Keeping Mikasa, Levi, and Hiss Clique aside, eight new Skins/Outfits have been added to Fortnite Chapter 4 Season 2. Some are re-designs, while others are brand-new. Although they are in the game's files, they may not be added to the Item Shop as soon as the downtime ends.
8) Dirt Bike and Port-A-Bunker unvaulted and weapon changes
Dirt Bikes have returned due to popular demand and just in time too. With ODM Gear and Thunder Spears now in the loot pool, players will need something fast to outrun opponents. In addition to these death-defying machines, Port-A-Bunkers have also been added to the loot pools and will offer some protection against weapons in battle.
It would seem that a new rarity of Kinetic Blade has been added to the game. This one will only hold two charges instead of three. On the brighter side of things, the Mythic Havoc Shotgun has been nerfed, and it now deals less headshot damage. Last but not least, the accuracy and hipfire rate of the Overclocked Mythic Pulse Rifle has been thankfully nerfed as well.
