Government forces received a tip not long ago that a major crime syndicate and a terrorist organization would be meeting at a bustling port. Eager to capitalize on the intel, a strike team was sent to raid the secret meeting. An informant tipped off the crime syndicate, however, and they vanished before the strike team arrived. The terrorists were not so lucky, and started a firefight at the meat packing plant used for the meeting. With the raid plans foiled, the strike team must suppress the terrorists and destroy their supply stockpiles.
It shares a similarity with Piazza, which was also originally clan S&D exclusive.
The codename for this map (in the files) was "Rottenmeat".
At the end of the trailer for "Slaughterhouse" on the Combat arms youtube channel, a scorpion tattoo is shown. Some players believed that this hinted towards a new Spiders Vs Scorpions Event. They were correct.
After the August patch, this map was released to be played by everyone, though only in the Search and Destroy game mode.
