The Armored Core series represents the most comprehensive mech simulation on the PlayStation, and Armored Core: Master of Arena was designed to uphold that detail-oriented, yet quick-moving, simulation tradition. Play through a new set of missions with a new story, and build up your Armored Cores (known as ACs) to get your pound of flesh as you take the role of a young AC pilot who's sworn vengeance on a mysterious, terrorist AC, who killed your family. All that matters is catching the AC with the 9-ball emblem.
