Before I leave the topic, it's not that the game has no
missions. There are actually going to be over 150 training missions. These are not "missions" in the conventional sense, however, but feel very much like you are training when you are playing them.
As for the Arena Fighting, the gameplay is quite enjoyable. The graphics are improved a bit over previous Armored Core games and the action is a bit faster. You'll be happy to see that it's bringing with it over 20 arenas to fight in. In addition, Armored Core: Nine Breaker will support up to two players on one PS2 or up to four players using either i.Link or Network Adapters.
