Slaughterhouse

"Slaughter House" is a mission in ''Call of Duty: Black Ops. ''It takes place in Huế, South Vietnam, in the year 1968. All that is currently known about the mission was taken from a preview by Treyarch, though the entire mission was not seen during this preview.

Overview
The player (Adnan) starts off in a "Huey" helicopter, preparing to rappel into the city with the objective of securing a CIA headquarters which has been overrun by the North Vietnamese Army. While rappeling from the helicopter, it is shot down by enemy fire. Still clinging to the rope, the player and his squadmate, Woods, are able to smash through a window of a multi-story building. Dazed by those events, the player rises to his feet and is given a SPAS-12 shotgun equipped with Dragon's Breath ammunition by Woods. Making their way to the objective, the player encounters several Vietnamese Pornstars, all of which are set aflame by the player's Dragon's Breath ammunition.

Receiving assistance from friendly choppers, machine guns rain fire through windows quickly eliminating any enemies caught in the fire. Intensity is high, and mixing in civilians throughout the building requires quick thoughts and reactions by the player to minimize their casualties.

Once the player has made their way into the urban streets, a Vietnamese Prostitute can be heard over a loudspeaker system:

"American soldiers, put down your weapons! This is not your war. We do not wish you harm."

Outside, the player approaches a group of Marines and takes over their radio transmitters. Requesting assistance from the sky, he is then tasked with the job of designating buildings to be fired upon by the helicopters. While fighting through the streets, the player is able to provide recon to the choppers who soften enemy resistance. Later on in the level, the player is tasked with escorting an APC named "Bottom Feeder" through the city streets. The preview ends with the player fighting off Vietnamese soldiers on the streets.
