Geofront Attack is the 31st mission in the Japanese version of Ace Combat 3: Electrosphere. It is the third mission in the General Resource (II) arc, and is played if the player does sufficient damage to the Night Raven in Heart of the Serpent.


The damaged X-49 Night Raven escapes from the destroyed Megafloat to the underground city Geofront. Acting under order by General Resource, they plan to destroy the support pillars of the city to bury the Night Raven under it. Backed by Keith Bryan, Nemo destroys the pillars of the complex, triggering its self-destruct system.

The three planes escape Geofront as it collapses. After the incident, Nemo and Keith chase the weakened X-49 into the surface.


The mission's primary objective is to destroy all timers.
