Ω System

Ω (Omega) System is an area in Xenosaga Episode II - Jenseits von Gut und Böse. It is the final story dungeon of the game.

Story
Upon recovering Proto Omega and the original within Labyrinthos on Old Miltia, Sergius activates the Ω System, a giant winged entity that completely destroys the planet. The party members make their way into the Ω System using the Elsa and fight their way through until they encounter Sergius, who uses Proto Omega to fire upon and destroy Albedo. After being defeated by the party members in battle, Sergius hopes to use Proto Omega again to destroy them, but the Testaments show up and kill him. The Testaments then revive Albedo. The party is able to escape when Ziggy punches through the wall and they flee onto the Elsa. The Ω System falls apart afterwards, being replaced by the Space Time Anomaly.
