Training Access is a room in the Torvus Bog in Metroid Prime 2: Echoes. It is a half-submerged corridor that serves as connection to the Training Chamber. On the first visit, the room is filled with Phazon particles, and the Dark Samus Intro theme can be heard. Upon emerging from the water, a blue light can be seen flying into the Training Chamber. It then materializes into Dark Samus herself. She does not engage Samus in battle, but maniacally laughs at her before disappearing.
- Training Chamber (via Blue Door, Multi-Lock Blast Shield on other side)
- Hydrodynamo Station (via Blue Door)
- Dark Samus
- "Morphology: Seedburster
- Exploding swarm of plantforms.
- Roaming pack of small, volatile plants. Expel seeds with great force when agitated."
- The door leading to the Training Chamber is briefly a white hatch - when Dark Samus's incorporeal form passes through it, it becomes a regular blue Door and will remain as such on all future visits to the room.
