Unrevisitable area

In video games, an unrevisitable area refers to a location that becomes inaccessible after a certain point, not counting games with a linear and irreversible stage progression. They are most frequently a part of role-playing games, and may contain items or accessories that can be missed. Some platforming titles that allow the playable character(s) to roam on world maps may contain levels that can only be accessed once, or around the start of the game.

List of unrevisitable areas

Donkey Kong Country Returns / Donkey Kong Country Returns 3D

The short segment before the Golden Temple gateway in Donkey Kong Country Returns 3D

In Donkey Kong Country Returns 3D, after using the Rare Orbs to grant access to the Golden Temple and, by extension, the Cloud world, the Golden Temple becomes the "Cloud Gateway" on the world map, and the player cannot replay the segment just before entering the temple. Instead, Donkey Kong is immediately transported to the Cloud world upon selecting the Cloud Gateway on the world map.
