Before I buy this Killzone Trilogy game, can I turn off strong language and blood/gore in this 3 Killzone games? If not, are the strong language with sounds at most in the games than words on the walls or so? Reason I am deaf that I cannot able to hear the words. If they don't have turn off for both, how much blood and gore were in those 3 games? Reason, I have 4 kids at age below 12 years old at home. Let me know, thanks.
