Infested Humans are zombie-like creatures that are only found in the ghost city of Zaragoza after Rahndestroyed the Latin Confederation headquarters located there.
Infested Humans are slow combatants that are only armed with their hands. While they are able to do some damage to Krukov and Reznov if they can get close, their slow speed makes them vulnerable to kiting, and they pose much less threat compared to Brutes or Bloaticks.
Infested Humans only appear as enemies in Intoxicated. They'll continuously spawn from the four infected Cloning Vats until they're destroyed. Exterminating them alongside all other wild Epsilon creatures in the city is the main mission objective.
