|Notable features||Morph Ball tunnel, Bendezium obstacle|
The Maintenance Tunnel is a room in the Phazon Mines, in the game Metroid Prime. It is a completely optional room that mostly consists of a Morph Ball tunnel. There is a Bendezium obstacle in the middle of it, so the Power Bombs are required to cross. It provides a shortcut from the Elite Control to the Phazon Processing Center.
