Armored Core: Last Raven is a mecha-based action game for PlayStation 2 where players assume the role of a Raven, elite pilots in a war between two factions, the Alliance and the Vertex. As a Raven, you must navigate the conflict by deciding whether to ally with one side or forge your own path, facing consequences from rival factions and other Ravens as you fight for survival and dominance.
Two powerful groups, the Alliance and the Vertex, are fighting for world dominance and victory hinges upon the `Raven` pilots. You are a Raven, an elite mech warrior who must choose sides between the fighting powers. Ravens face the ultimate decision in the fight for survival, either to fiercely defend their chosen side or fight alone and face the wrath of all Ravens.
