Armored Core: Project Phantasma

A Raven operating out of Isaac City receives an unusual order. Not only is the request vague and cryptic, simply stating, "Infiltrate the Amber Crown underground city complex," but it is also sent directly to the Raven in question, bypassing normal communication channels, without anyone else seeing the message. Neither the sender's name nor the company affiliation is mentioned, but the promised cash reward is enormous. Due to the size of the amount, the mission is of course extremely dangerous, but Raven is not the type to back down from any challenge. With his interest piqued, the raven climbs into the AC and sets off for Amber Crown.
