The city was one of the final areas visited by the AI Nemo in the Intercorporate War simulation. In nearly all scenarios, it would destroy the Ouroboros' UI-4053 Sphyrna after the destruction of the floating city of Megafloat, prompting it and a wingman to pursue and battle them inside the city.
In the Neucom path, Nemo and Fiona Fitzgerald pursued Rena Hirose and Abyssal Dision into Geofront, navigating through its tunnel network until they reached the core. Backed by hacking from Simon Cohen, they succeeded in taking Rena down, and killed Dision shortly afterwards.
In the General Resource path, Nemo and Keith Bryan pursued Rena's X-49 into the core of Geofront and destroyed various support pillars in an attempt to kill Rena by triggering the city's self-destruct mechanism. The Night Raven, though badly damaged, survived and escaped.
- Geofront shares its name and nature with an underground city from Neon Genesis Evangelion.
