Crater Tunnel B is a room located in the Impact Crater region of Metroid Prime. It is the room before the encounter with the boss Metroid Prime. It is also the room in which Exo Skip starts, exploiting a Secret World that makes use of a small gap in the room's boundaries to get Out of Bounds.
Exo Skip
Exo Skip is a trick discovered by gdVertigo. By luring a Metroid into the room, you can get Repositioned out of bounds if the Metroid is positioned properly and the Samus rolls into the corner at the appropriate time. This trick allows you to skip the Exoskeleton Phase of Metroid Prime.

Unmorphed SW
It is also possible to perform this SW while unmorphed, though this isn't widely used. Setups that use the Morph Ball are more common, and therefore more widely recommended. Since the Morph Ball is used to lure the Metroid into the room, this does not skip that requirement.
