DIABLO III is a fantasy role playing video game in which players choose to be one of five hero characters who must defend the land of 'Sanctuary' from the forces of evil. The game was classified '15' for moderate bloody violence.

The BBFC's Guidelines at '15' state 'Violence may be strong but should not dwell on the infliction of pain or injury. The strongest gory images are unlikely to be acceptable'. In DIABLO III, players battle against a whole host of fantastical creatures using a variety of weapons or spells. When this occurs, the creatures are seen to evaporate in a large puff of blood. However, the images lack any real detail and do not dwell on pain or injury.

DIABLO III also contains infrequent mild language.
