Great Tree Chamber is a room in Metroid Prime accessed by Great Tree Hall. Samus needs the X-Ray Visor to reach this room. She first goes to the Great Tree Hall and uses the X-Ray Visor to see invisible platforms used to get to this room. The platforms can be seen without the Visor however, as rainfall in the room bounces off the platform's surface, allowing Samus to deduce their position. There is a Missile Expansion in this room.
- Missile Expansion
- No obstructions are in place. The Missile Expansion is not hidden.
