It's been 20 years since the Earth Government and the Corporations battled for supremacy. The majority of humanity lives beneath the surface of the planet, relatively safe from the continuing struggle. A new and mysterious entity has entered the picutre, however, snapping up all the available Ravens for intense missions that only their custom-built Armored Core Units can handle. As a Raven, you know there's always another mission waiting for you - does it really matter who, or what, hires you? For all the new parts and weapons out there for you to earn in battle - we didn't think so. But just the same, keep your back covered, Raven.
