The Infected are men and women who contracted the Harran Virus that spread through the entire city of Harran. They possess reduced higher brain function, attacking and subsequently infecting any uninfected targets around them on sight, mainly with their arms or with handheld weapons. The combat system in Dying Light allows the player to dismember and incapacitate Infected reducing their offensive capabilities or even completely preventing them from attacking.
The most common Infected share similar biology to humans. When striking biters with blunt weapons it is possible to determine that their bones are structured almost identical to uninfected humans. However, the Harran Virus can alter the infected's biology when the sun goes down, increasing their motor coordination and sensory capabilities to make them deadly hunters.
Special infected are a different story; in these cases, the Harran virus causes severe mutations, from the UV-vulnerable Volatile to the physically enhanced Demolisher. It is unknown what determines the rate at which mutations occur. However, it is speculated such would require either significant time to alter their biology or the mutagenic rate is rapid and requires vast amounts of energy to generate new cells causing their increased aggression and hunger.
In Dying Light, the behavior of the infected depends on the «Day/Night cycle». During the day, the infected are sluggish and cumbersome, and demonstrate the inability to climb or run after the player (except for Virals). During the night the infected are stronger and more agile making exploration more dangerous for the player.
