Parents will want to steer their children clear of this one. It's excessively violent with blood, explosions, and the wholesale slaughter of innocent bystanders. Not cool for the kiddies.
Fans of sandbox gaming may discover just what a hollow pursuit it is. Sure, there are cars to toss at people and grenades to send them flying in every direction, but doesn't the constant murder get old after a while? It's not like there's anything to do other than shoot people in the streets, and even the most socially maladjusted nihilist is sure to tire of it quickly.
Deaf and Hard of Hearing gamers should be fine. There aren't any vital audio cues, and key information is written onscreen. Even the random audio messages that pop up on the soundtrack are subtitled.
