Parents be careful with this one, given the game's violent content. It's not excessively bloody or gory, but it does contain quite a bit of murder, antiseptic though it may be.
Splinter Cell Fans looking for some tactical stealth action while waiting for Sam Fisher's next adventure, here's the verdict: you could do a lot worse.
Deaf and Hard of Hearing Gamers will have trouble with some of the stealth sequences, as they won't be able to tell how much noise they're making. All of the dialogue and story sequences are subtitled, though, so it's kind of a mixed effect.
