Graphic Content Filter

The Graphic Content Filter is a feature which significantly reduces mature content such as blood, violence and strong language.

Call of Duty: World at War
The profanity is more focused on and completely removed, but there is no reduction in any online content. There will be no meat splatter if the player shoots a person but only a small cloud of blood. Blood and gore is still present in "Blood and Iron", as it is a vehicle level. In Zombies, it is still possible to decapitate a zombie, but there is no blood or meat chunk splatter. It is still possible to create crawlers, however their legs will stay connected to their bodies and will drag behind them as they move. Split Screen is completely unaffected, and online is reduced to less common than split screen.

Cursing is also very limited, and usually swear words such as "fuck" are replaced with less profane versions, such as "damn". Some words are even completely taken out.

Call of Duty: Black Ops
In this game, blood and gore are completely removed from all offline interactions and multiplayer. In campaign, "shit" and "fuck" are completely removed.

In Zombies mode, when playing solo, there is no blood from damaging zombies and no gore whatsoever. The opening cutscene and the outro in Call of the Dead are not edited, however. Note that blood is not caused by weapons like the knife or M1911.

Call of Duty: Black Ops II
Remains mostly unchanged from Black Ops, just that most profanity is muted instead of replaced. All blood and gore is turned off with the filter enabled and several violent cutscenes have been retained but only see pixelated images to not show anything explicit. The word "God" and the related (such as "damn it") have been muted to not offend anyone adhered to a religion. It is still possible though to make crawlers on zombies in the map Buried by using the head chopper, although their legs will still be attached.

Examples

 * In "Semper Fi", the player cannot look around when the Marines are getting tortured. Also, when Sgt. Sullivan says "Tojo's at home in this shit", he will instead say "Tojo's at home in this muck" as well as the Marine saying "Looks like a temple or something" as opposed to "Looks like a temple or some shit".
 * In "Numbers", the torture scene at the beginning is entirely gone, and near the end of the mission, instead of Clarke being shot in the head, his eyes roll back and he dies.
 * In "Payback", Frank Woods says "Damn!" instead of screaming "Fuck!" during Russian Roulette.
 * The swastikas in Kino der Toten scattered around the map are replaced with eagles.
 * In "Pyrrhic Victory", the scene where the trapped man is burning alive has been removed. He is not shown screaming or smashing his arms against the glass, but Mason still attempts to break the glass.
 * In "Time and Fate", Woods' line in the beginning "Let's not fuck around here boys, let's smoke this bastard." has been changed to "Let's not fool around here boys, let's smoke this bonehead.".
 * In "Time and Fate", when using a Machete to kill enemies, there will be no blood splatter or gore.
 * In "Suffer With Me", Hudson's line "Fuck! Okay, me, do it... Do it!" has been completely muted for an unknown reason, rather than just the F-word itself (probably due to time constraints).
 * In the "good" ending of Call of Duty: Black Ops II, when Menendez slams his head to the TV several times, his entire body including his face will be censored.
 * In Old Wounds, when Woods' team discuss the plan with Rahmaan, "bullshit" is changed to "lousy".

Trivia

 * In "Revelations" on the Wii, Jason Hudson's line "The Russians fucked you up" is not censored, due to the fact that the level is actually played as a cinematic on the Wii (like U.S.D.D.).
 * By default, the German versions of World at War and Black Ops have gibbing disabled because it is against the German youth protection law. This means that in the German versions, the GCF does little more than censor the profanity.
