Clickers appear less human than runners and stalkers, with faces that are completely split open and scarred by fungus developed from their infected brains, often only leaving behind a maw of jagged teeth. By this point, whatever clothes the host may have been wearing are mostly tattered and destroyed. The skin is covered in mold and scaly fungal growths. Most notably the eyes of clickers have been completely destroyed or covered due to advanced fungal growth, leaving the host completely blind.
