Appearance: Sector 1. The most common type. Upon spotting a human, they attack by swinging their fists. They have white eyes.

Appearance: Sector 1. Infected entities armed with steel shields and tonfas. They have orange eyes. When they spot a human, they bang on their shields and approach slowly to swing their tonfas. They were originally soldiers deployed to protect refugees in the camps.

Appearance: Sector 1. They have eyes that glow orange. These entities wear gas masks and are armed with blunt weapons like axes or sledgehammers. Unlike others, they walk slowly. They possess a degree of proficiency with their weapons. If detected, they will strike you down with their heavy armaments.

Appearance: Sector 2. Armed with a circular chainsaw and wearing a gas mask. He has red eyes. Originally a firefighter who came to extinguish a massive blaze, he eventually became infected and lost his mind. When first encountered, he is seen sobbing, hunched over a comrade's corpse; if detected, he will scream and drive the chainsaw into your body. Inside Mikhail's coat is an old photograph showing his normal self before infection, along with his wife and son.

Appearance: Sector 1. A member of the Quick Response Force armed with a shotgun. He wears a gas mask and has red eyes. He is the only one among the infected capable of conversation. His voice is very raspy. Although Gilbert's mind remains intact despite being infected, he cannot control his body due to the virus's influence. He guns down everything in sight, including other infected, with his shotgun.

Appearance: Sector 1. Equipped with a glowing white claw on the left arm, its skeleton deformed during infection, causing the mouth to split into two halves lined with rows of sharp teeth. It is extremely agile and possesses superior combat skills. It was a squad leader, just like Gilbert. You will rarely encounter this thing. It's better that way.

Appearance: Sector 3. A Russian member of the RIF. He wears a ballistic helmet capable of stopping bullets from the front and full-body armor, armed with a machine gun and a sledgehammer. Removing the helmet reveals a man with a shaved head. Komarek portrays the MGF as the aggressors. He criticizes the values of the Republic of Menlo and the MGF, claiming he is saving his fellow citizens and comrades while the MGF refuses to rescue them and seeks only to kill. However, despite knowing the research facility had already collapsed, he frames the operation as a cleanup and massacre by the MGF, making no mention of his own actions or their consequences—even though he illegally infiltrated the infected zone disguised as a PMC mercenary and slaughtered facility personnel and MGF soldiers. His frequent mentions of the President demonstrate a thought process conditioned to prioritize national ideology and the leader's will over personal judgment.

Their goal is to safely rescue Lasonian citizens from the infected zone. At first glance, they appear to be deployed with a legitimate cause, and Lasonian soldiers perceive them as such. However, their unauthorized infiltration into the infected zone without Menlo government permission causes chaos in the quarantine, and their combat with the MGF at the nuclear plant—where there are no rescue targets—makes them highly suspicious. If you belong to the MGF, you must prepare for battle. [Unit Types] Infantry: Armed with rifles. Machine Gunner: Armed with light machine guns. They wait in position to eliminate enemies with a high rate of fire. Medic: Heals soldiers. Armed with a rifle. Breacher: Armed with shotguns. Wears an Altyn helmet.

Appearance: Sector 3. Wears a thick hazmat suit and carries a chainsaw. His eyes glow yellow. Originally the head of security, he is now a chainsaw-wielding maniac who has lost his sanity. If he spots you, he will raise his chainsaw and charge to cut you in half.

Appearance: Reactor Unit 4 Entities subjected to overwhelming levels of radiation. Their entire bodies are red, and their fingers have mutated into sharp points. Deep within the reactor, there are areas covered in spread-out flesh. In severe cases, multiple mutants may be found fused together on the floor. If they catch you, they will tear you to shreds.
