To fit the OG theme, Fortnite changed the Item Shop to what it was back in Chapter 1, but many fans believe that this model is now outdated. Fortnite went back in time, allowing fans to enjoy the Chapter 1 map and items pool for a month, which means it'll come to an end at the start of December. Then, the game will most likely go back to its usual Chapters-and-Seasons system and continue with the start of Fortnite's Chapter 5 Season 1.
