According to ESRB, this game contains: Mild Violence
Parents have almost nothing to worry about with this title. While the game has garnered a Teen rating, the violence is very mild and totally cartoonish. Ratchet's weapons rarely look like real guns, and there's no blood or guts anywhere to be found in the game's lush graphical environment.
Fans of the original Ratchet & Clank are going to want to play this one—it ups the ante in just about every way imaginable, and stands as one of the best gaming moments of this generation.
Casual gamers will also want to experience this game—it's accessible without being too easy, and can be played in either marathon gaming sessions or small increments over a long period of time.
Deaf and Hard of Hearing gamers have nothing to worry about—the game's elaborate (and hilarious) voice acting comes with an option for subtitles in the game's menu system.
