There are a number of changes in the German version. The Windows version requires a Steam verification and is region locked, i.e. an uncut version can't be activated when the player has a German IP address.
- The cutscenes were heavily cut, e.g. violent scenes, attacks on unarmed people and drug use. The screen goes to black with the text "Wir bitten um Verzeihung - sehr böse Dinge passieren hinter diesem schwarzen Bildschirm!" ("Many apologies - very bad things happen behind this black screen!"). The audio and subtitles are still there.
- All blood effects (except when shooting meat and in cutscenes) were removed.
- Ragdoll effects on people (except after explosions and when they are hit by a car) and corpses were removed.
- Killed enemies disappear almost instantly. This means the possibility to revive killed people with the defibrillator is also gone.
- There are no flames on burning people; only black smoke. They also don't scream.
- People only leave money behind if completely killed.
- The option to take a human shield was removed both for the player and for the AI. This affects some missions.
- During the fight club sequences, the finishing move quicktime events when an enemy reaches the bottom of his health were removed. Players have to finish off all enemies the hard way.
- Likewise the finishing moves with the katana were removed.
- The respect growth for performing combat moves like headshots was removed.
- Some activities were removed: the amok drive with a burning vehicle, Fuzz (wreak chaos for a TV reality show), vandalism (earning money by destroying property) and being the bodyguard of a celebrity. Because of this, some of the unlockables are not reachable for German players.
- The mini games Zombie Uprising (arcade) and drive-by were removed. During the pimping mini game, the screams of lust were removed.
- During the first main mission, the player has to kill a prison doctor to progress. This was removed in the German version.
- The cheats for getting the flame thrower, chainsaw and explosive charge were removed.
- The "Zombie Carlos" companion was removed.
- The texts in the German version differ from the German texts in the regular version, e.g. the game avoids the words "töten" ("kill") or "Nutte" ("hooker").
- Various "number of killed x" statistics were removed.
- Xbox 360 version: a few achievements, mostly related to missing game content, were removed and the gamerscore divided between other achievements.
