Night Hunter - As a player-controlled infected encountered as part of Be The Zombie (when playing as the Night Hunter) as well as during game invasions (when playing as humans), this is almost an entirely different entity altogether.though their feeding grounds are guarded and patrolled by the Volatiles and alerting a Bolter will automatically engage a pursuit from the nearby Volatiles. Hunting them down and scavenging their tissue can be very profitable when sold to traders. They have the same cone of sight as most enemies, and are best carefully approached from behind and killed in one hit to avoid the fleeing altogether. They come out at night mainly to feed on corpses (marked as Bolter Feeding Grounds on the map) and remain stationary and unaware for the duration of the night. As the name implies, they bolt/run away from the player upon seeing them. Bolters - Bolters are the only targetable enemy type in game that have no hostile actions or aggression towards the player.though their speed and agility roughly matches that of the player, and are much harder to outrun than their Viral counterparts.
They have the same cone of vision as Volatiles do, but are only roughly as dangerous as Virals by themselves. Passing by Biters in a Pursuit increases the chances of a transformation, and transformed Night Walkers can start a Pursuit (calling in Volatiles and more Night Walkers). Night Walkers - Initially similar to the Biters in appearance and function, the Night Walkers are effectively Biters until they change into Night Walkers with a rather violent and noisy transformation (during which they must be immediately killed to avoid a Pursuit).On Nightmare difficulty, a good swat from a Volatile can do roughly 120 damage, and they have the equivalent of thousands of health, meaning inexperienced or low-level players should avoid them at all costs. Any attack on a Volatile immediately results in a Pursuit (calling more and more of them to come investigate/attack).
