The violence takes the form of the player's involvement in gun battles with various enemies in which an array of contemporary weapons such as automatic rifles, pistols and grenades are available, along with larger items of artillery and tanks. The player can also access bladed weapons for stealth attacks and hand-to-hand combat. The battles are intense and conducted from a first-person perspective with impacts registering as bloody splashes with further sight of blood decorating the various environments in the aftermath of fighting. Bullet impacts or explosions cannot, however, cause dismemberment and there is no opportunity for the player to inflict further damage on an enemy who has been killed. Whilst undoubtedly strong and bloody in terms of specific detail and cumulative effect, the violence in the majority of the game would have fallen within the allowance of the Guidelines at '15' which state that 'Violence may be strong but should not dwell on the infliction of pain or injury. The strongest gory images are unlikely to be acceptable.'

The '18' category was, however, deemed more appropriate for a particular mission in which the characteristics of the violence differ from the rest of the game. In this mission, the player has infiltrated the terrorist group and joins them as they execute an attack on innocent civilians at an airport. The violence is bloody and intense, and aggravated by the fact that, unlike other combat sequences in the game, the civilians cannot fight back and are massacred. The player character can choose to join in the shooting or do nothing in order to preserve his cover, but he cannot intervene to prevent the massacre by shooting the terrorists since he is then 'discovered' and is very quickly overwhelmed and killed. The evident brutality in this mission does carry a focus on the 'infliction of pain or injury' which, along with the disturbing nature of the scenario it sets up, was felt to be more appropriately placed at the adult category and it is worth noting that the game itself gives the player the option to skip this mission without penalties to progress or achievements. Although the content of this mission was recognized as having the potential to offend, it was not felt to present a significant harm issue at '18' that would require further intervention.

The game also contains mild-to-moderate language with uses of 'shit', 'bollocks', 'ass', 'whore' and 'bitch'.

There are a lot of little kids playing cod but if you took them away there won't be as many people to play with which could result in long waiting times to find a game...
