A number of infected that were visible in concept art were cut from the final game. These include:
• An infected with a large colony of rats bursting from its stomach, likely to be found in the sewer.
• A slow but strong giant called "Meat Wall" (which resembles a cross between a Boomer and a Tank).
• An infected named "Claws", which was possibly intended to be a male version of the Witch.
• An infected pig named "Hell Hog", likely intended for Blood Harvest.
