Main Research

Main Research' is a large room in the Sanctuary Fortres in Metroid Prime 2: Echoes. Upon first entry, some sonic emitters are activated, and must be destroyed to raise an Echo Gate and allow access to a portal to Staging Area. Another exists at the bottom of a chamber in the middle, which houses the Caretaker Class Drone.

Glitch
This room is responsible for the most fatal glitch in Echoes. Should Samus, for any reason, leave the room before destroying all sonic emitters, the door will be locked permanently and she will not be able to continue until she either restarts the game or performs a Kip Dash. If she hasn't saved the game, she can also restart from the last save point.
