Collapsed Tunnel is a room in the Temple Grounds area of Metroid Prime 2: Echoes. The room is named as such because the main tunnel has caved in, blocking access. PFC M. Veroni's body is trapped in this rubble, it would seem that he perhaps caused an explosion that killed him. Another tunnel only accessible by small objects provides another way through. Two Green Kralees patrol one of the doors. The Dark Aether version of this room was Lake Access.
