Crater Tunnel B

Crater Tunnel B is a room in the Impact Crater. It appears in Metroid Prime.
==Description==
This room's most notable feature is a maze of "natural" Phazon variant Spider Ball Tracks, hanging over a layer of Red Phazon. It is entirely possible to simply run across the Phazon and Space Jump onto the ledge on the far side, rather than using the labyrinthine Spider Ball Track, although this will cause high damage to Samus's Power Suit, and is not recommended due to the fact that the Metroid Prime itself is in the next room. It is the only room to contain a set of Spider Ball Tracks of this version. They appear to be more organic than other models, whether they were grown as part of the room or placed there is unknown. It is possible to stand on certain parts of the walls that are jutting out, including on top of certain Spider Ball track areas.
==Connecting rooms==
*Phazon Core (via Red Door)
*Phazon Infusion Chamber (via Red Door)
==Development notes==
The room's internal name is 00_b_crater_connect. Its name references being listed as a second connecting hall, appearing after Crater Tunnel A.
This room has an unused layer in the game's files, labelled "Don't load", which contains unused enemy placement removed in the final. Among the removed enemies is a second batch of Lumigek and a Phazon Burrower, a creature that appears nowhere else.
Loading the room with these enemies in places gives off the impression that the room was meant to be slightly harder travelling through the hall. The Phazon Burrower is set near the center of the Red Phazon pit and will occasionally pop out to fire at Samus whether she is near the creature or above it on the tracks. Parts of its antenna can barely be spotted from above ground when it is hiding underground. The Lumigek swarm swarm around the Phazon Pit and the final two tracks nearby that lead up to the Phazon Infusion Chamber, blocking safe passageway to the door. A Power Bomb can be placed in front of the swarm on the nearest track to eliminate the swarm long enough for Samus to pass through the rest of the tracks safely during the bomb's duration before more Lumigek respawn. Despite these additional enemies, Samus can simply choose to ignore the enemies and rush through the room just as in the final. The Phazon Burrower can be quickly killed if it is in the way.
