Mobile Suit Gundam: Extreme Vs Force's story mode is a prequel to Gundam EXA, set within "Project Force"—a plan to help humanity evolve and avoid extinction by running virtual combat simulations across Universal Century timelines. Two AI navigators, Aire and Tereno, guide a human personality through these simulations. As the player progresses, the project's control program reveals its intent: to force human evolution through manufactured conflict. It then attempts to take control of both navigators and initiate a colony drop as a final measure. Aire and Tereno sacrifice their own identities to stop the station from falling, leaving the player with fragments of memory and a name: ex-.
