According to the ESRB, this game contains: Fantasy Violence
Parents don't have anything to worry about as far as content goes. The only characters in the game are unmanned robots, and although they do use a wide range of weapons to attack each other, there is no blood or gore, and nothing is at all graphic. The worst it gets is seeing a robot give off sparks and puffs of smoke. There is no questionable language and no sexual content whatsoever. It's a completely clean game, although the caveat here is that it will be impossible for most young ones to play since the focus is on highly technical and cerebral action. Kids not yet in their teens will likely be mystified.
Action gamers should stay away. Controlling a robot manually is possible, but not recommended due to the unwieldy set up and awkwardness of using the PSP for this game. It's all about the mental with this UMD.
Armored Core fans are strongly urged to check out this game. Most of it will be familiar, but the new addition of AI programming and control is all-new and gives the series a radical makeover structurally. There are no missions, only one-on-one matches, but using the artificial intelligence provides a kind of challenge and substance that this series has never had before. Even for players who think they're tired of it or have already sworn it off, it's still worth checking out and comes highly recommended from someone who has played every single game in the series.
Multiplayer fans will be able to take advantage of local Ad Hoc matches, but the developers have still not implemented truly online play. It's disappointing, but not unexpected.
Deaf and Hard of Hearing Gamers will have no problems at all. All dialogue information in the game is accompanied by text, and there is a wealth of supplementary information available to be displayed on-screen. I played a significant portion of the game without any sound at all, and encountered no problems. Thumbs up.
