It has officially been rated T by ESRB. Unnofficial Steam M rating is innacurate. Community aside (just mute them) its just basic non graphic blood puffs
Most of your playtime will be nonviolent running. Players are only likely to get a handful of kills per match. There is nothing graphic or disturbing about the deaths. Just cuz a game has shooting in it, especially if its for the sake of survival, doesnt mean its going to derange anyone under 18. If killing in a T rated game like Uncharted wont derange a young teen than this wont either. Game is very basic deathmatch, yet in a huge open world where vehicles items and gear are scattered at random. I like how despite the aesthetic the gamendoesnt attempt realism. Health bars are adequate, damage is balanced, and bullets go wherever you aim. Younger players may be bored. As longs as you dont expect anything fantastical or large scale battlefield devastation, pretty much anything can happen if you are patient enough. Every online game has its toxic players. Even the kid friendly Overwatch.
