According to ESRB, this game contains: Mild Language, Violence
Parents don't have much to worry about. It's a violent game, but the violence is mainly perpetrated against robots, and is completely bloodless. As the Teen-rating suggests, it's appropriate for kids 13 and over.
Fans of the films will want to avoid this game like the plague, and not just because it's about the worst film in the franchise. It doesn't bring anything new to the mythology, just uses it as a setting for some very dull gameplay.
Fans of classic gaming take note: it features Missile Command (because of the thematic opportunity) and Centipede (because, um people like centipedes?). Really, it seems like Battlezone would have been a better choice for the subject matter, but who can understand a corporation's reasoning?
Deaf and Hard of Hearing gamers are in for some bad news: there's no subtitling option that I could find, leaving the game's plot even more incomprehensible than it already was. There aren't any audio cues of note though, and mission information is displayed onscreen, so the game is still playable.
