Salty Towers is a mix of Tilted Towers from Chapter 1 and Salty Springs, which already was featured in Chapter 2 before Season 5. The new Towers are located east from the Zero Point.
Nobody could’ve known that Tilted Towers are coming back, but it happened. Unfortunately, only a part of the old city made it to Chapter 2 Season 5 and replaced a part of Salty Springs. The new location features the big gray building in the middle, the clock tower and some other houses from Tilted. The total amount of houses from Tilted Towers is 6.
