In the last mission, two AI-controlled X-49 Night Raven mainframes and a UI-4054 Aurora manned by Abyssal Dision escaped from the Ouroboros' airship UI-4053 Sphryna as it fell towards the Usean ocean, with one of the X-49s using its laser cannon to sink the seaborne city. Said aircraft then escaped with Dision into the submarine city of Geofront through its entry tunnels, leading to a pursuit by UPEO AI Nemo through the city's tunnel networks.
