Zombie (Half-Life)

Zombies are a commonly faced foe in Half-Life as well as its sequel, being a regular human with a headcrab latched onto its head, mind-controlling them to do hostile actions.

Standard
Being the most common and useless type of zombies, the standard zombies are mind-controlle scientists that only attack with swipes. While their legs can be blown off, they can still survive this attack and will relentless crawl towards their foe until death.

Gonome
Being a more mature evolution of the standard zombie, gonome zombies have much more defining muscle mass on them from a mutative growth and attack with swipes, gut throws, and chest bites.

Fast
Fast zombies are zombies possessed by fast headcrab. These unqiue headcrabs completely digested their hosts skin layer, making them walking shapes of muscle and bone. As one can judge from their name, fast zombies are much more faster and agile than regular ones.
