Armored Core: Nine Breaker brings back the super strong `Nine Ball` mech who appeared in the original PlayStation Armored Core. Those who can defeat `Nine Ball` (which likely means you if you see the end credits of Nine Breaker) are labeled as the true most powerful mech around, the `Nine Breaker.` In Armored Core: Nine Breaker, players play through two main modes of play: training mode and arena mode. Training mode features 150 programs that test players' skills. Players can try out programs that focus on attack, defense, movement, `technic,` `special` and `overall.` Each of these areas are further divided, with attack comprised of multiple tests in accuracy, power, judgment, `hit - single` and `hit - melee.` Arena mode is a battle mode in which players take on other mechs in battle. Mech modification, the series' bread and butter, is of course featured heavily in Nine Breaker.
