According to ERSB, this game contains: Blood and Gore, Intense Violence, Strong Language
Parents should keep kids away. The game is all about violence, centering around killing opponents in various ways. There is some salty language to be heard, the females are all scantily-clad and buxom, and opponents explode into red, wet chunks. Obviously, this is not kids' stuff.
Fragging fans will probably find a lot to like here. There are a ton of options as well as full Live connectivity. The graphics and framerate are sharp, and the new melee combat really does add an all-new dimension to play. If this is your thing, this is a worthwhile package… as long as you're not playing it for the weak single-player mode.
Deaf and Hard of Hearing gamers get full text (enabled in the options menu) so the dialogue during cutscenes is fully accessible, but they will miss out on a lot of the audio cues (weapon firing sounds, etc…) that help during gameplay. However, using only third-person mode helps reduce the reliance on audio, alleviating the situation somewhat.
