PEGI 18: The adult classification is applied when the level of violence reaches a stage where it becomes depictions of gross violence and/or includes elements of specific types of violence. Gross violence is the most difficult to define since in a lot of cases it can be very subjective, but in general terms it can be classed as the depictions of violence that would make the viewer feel a sense of revulsion. Descriptors shown on the back of packaging indicate the main reasons why a game has received a particular age rating. There are eight such descriptors: violence, bad language, fear, drugs, sexual, discrimination, gambling and online gameplay with other people.
