The slaughterhouse is where meat wagons and abominations are created. Meat at the slaughterhouse is used to serve the twisted purpose of the malevolent Scourge. Grotesque, monstrous abominations are pieced together and instilled with the single purpose of killing. Meat wagons are constructed to lob plague-infected body parts at the enemy.
Patch 1.06 (2003-06-03): Most advanced technology structures had their build times reduced. This reduction ranged from 20 seconds for especially underused structures, to 10 seconds for less underused structures. For instance, the Slaughterhouse builds 20 seconds faster now, while the Arcane Sanctum build time was only reduced 10 seconds.
