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.
- 2 Green Kralees
- "Morphology: Green Kralee

- PFC M. Veroni
- "I think Haley's losing it. He talks to himself all the time, and he won't sleep. He almost shot me on watch the other night. I think he thought I was one of those things. I talked to the doc about taking him off the line, and he told me we need all the help we can get. That's true, but if he goes berserk and kills a bunch of us, that won't be very helpful."
- Unknown biomass
- "Object scan complete.
- Object is composed of nutrient-grade biomatter, protected by thick exobarrier and tensile webbing. Possible source of nourishment for local bioforms."
