How bad is the language in prototype

Considerably foul, using several tier 2 curses (sh*t, b*tch, etc.) but it doesn't use the f-word. You have the option to turn off subtitles if you don't want to read it and turn down the volume if you don't want to hear it. BTW, the violence/gore should be your primary concern, not language, as people are literally torn to bits, beaten into pulp, and "eaten."
