Research Entrance

Research Entrance is a room in Phendrana Drifts in Metroid Prime. It is a large room containing many pillars, wires and metal walkways and a few crates, with an upper metal-floored level. When Samus enters this room, the doors lock and Space Pirates attack; these must be defeated to unlock the doors again. On later trips, the Space Pirates are replaced by Shadow Pirates, and the doors do not lock.
