Enter Dision is the third campaign mission of the Japanese version of Ace Combat 3: Electrosphere. This mission introduces two new characters into the plot: Abyssal Dision and Keith Bryan, two ace pilots from General Resource.


"Currently, Neucom's military activities have begun to quiet down, and USEA has maintained a semblance of peace. However, in case the conflict between the two sides escalates, SARF and General Resource have decided to conduct a joint training flight. Although it is not a real battle, in order to better coordinate with the General Resource unit, being careless is not an option."
Ace Combat 3: Electrosphere - Namco Official Guide Book


Neucom's momentum has been weakened, but we cannot be careless. Accordingly, in preparation for the next development, we have come to perform join exercises with General Resource's forces. Don't hold back just because this isn't real combat!


We've still got some work for you, too, so don't slack off now.
