Armored Core 2: Another Age - PlayStation 2

In an environment such as this, an underground of mercenary factions flourishes. Enter the Ravens, the pilot wing of the Armored Core. They battle in government skirmishes, as well as public arenas, for profits, much like Rome's gladiators. If you can become a high-ranking Raven, your influence will reach beyond the public to affect the fate of the planet. Your mission then is to rise through the Raven ranks and chart a destiny for earth.
