Hatred has been rated “Adults Only” by the ESRB, the ratings board for the United States and Canada.
“Well, I’m not quite convinced why Hatred got AO rating while it lacks any sexual content, but it’s still some kind of achievement to have the second game in history getting AO rating for violence and harsh language only. Even if this violence isn’t really that bad and this harsh language isn’t overused,” a developer wrote on the official forum for the game.
“I would prefer to get a standard M+ rating, because with AO we will have problems to to get to consoles in the future, but on the other hand I think you guys (our fans) would be disappointed with it.”
It’s rare for the ESRB to rate a game as AO for its violence and language rather than sexual content, and the rating also means it will not be published for consoles, and Steam currently has no AO-rated games for sale.
