The most basic and common enemy. Upon detecting a player, it runs toward them. It can be easily dispatched by shoving it and aiming for the head. It staggers briefly when hit. Unlike other variants, it has white eyes.

Like the Lurker, it runs toward the player upon detection, but it moves faster and rolls to evade when attacked. It gains high defense during this roll. If its health drops below 150, it collapses with a scream, only to resurrect shortly after with a monstrous roar.

Armed with a riot shield and a machete. Upon detecting a player, it approaches slowly while banging on its shield. The shield blocks all bullets. Since it always keeps the shield facing the player, the most efficient way to kill it is to shove the shield aside first.

A unique entity that also attacks the infected. While the infected will fight back against Gilbert, they will prioritize the player if one is detected. He primarily uses a shotgun and a combat knife.

When shot, it teleports a short distance and staggers, or beats its chest and laughs mockingly, gaining high defense during the animation. It has long claws on its hands; if the player's health is below 30, it performs a brutal execution with its claws.

The mini-boss of Sector 2. Armed with a circular saw. He spawns inside the Logistics shutter area. If the player's health is below 30, he executes them with his circular saw.

An enhanced version of the Slasher. He begins appearing from Sector 3 onwards. He carries a chainsaw and attacks with it.

The boss of Sector 3 and a major hurdle for solo players. He wears a ballistic helmet that blocks frontal headshots and moves slowly while spraying bullets from a distance. If a player gets too close, he stops firing, rushes in to knock them down with a kick, and executes them with a machine gun.
