Violence is a content descriptor used in PEGI 7, 12, 16, and 18. It signifies that there may be depictions of violence, blood, and/or gore in a video game. It is the most commonly used content descriptor used by PEGI since its creation in 2003. Gratitudious killing (killing with no mercy) generally is only used in an 18-rated game. Most games with violence toward humans (non-graphic) or graphic non-human violence usually receive a 12 rating, and rarely a 16.
