The Backpack can be used in a Mission, Homebase, and the Armory. The Backpack is used to hold items and resources such as crafted schematics and world resources. It can be upgraded using Skill Points.
The maximum backpack size is 210 with standard play, and up to 250 if you:
- Enable 2FA +20
- Owned Limited +10 or Ultimate Edition +20
- Logged in during Fortnite's "Pre-Launch" +10
The extra backpack slots offered in the Limited and Ultimate Editions of Fortnite can no longer be obtained, since those editions of the game will no longer be offered as of v13.20.
Additionally, the pre-launch backpack expansion was only given once and can also no longer be obtained.
