Brad Gallaway reviews Armored Core Nine Breaker, and has this to say:
"I've played and finished every Armored Core game since the first on the PlayStation back in 1997. Since I've been writing for GameCritics, I've reviewed four of them: Armored Core 2, AC2: Another Age, AC 3, and Silent Line: AC. If you're reading this review now and have even the slightest interest in checking out what this long-running series has to offer, do yourself a favor and a check out any (and I mean any) of the other games in the series before trying Nine Breaker. In fact, just forget that this game even exists. Without a doubt, this is the worst Armored Core that's ever been produced. "
