No More Room in Hell 2 — All Zombie & Enemy Types

A dangerous zombie in No More Room in Hell 2 is defined by the problem it creates: speed, alarms, infection gas, armor and increased health each demand a different response. Here is every enemy type and how to counter it.

Standard Zombies & Walkers

Standard zombies build pressure through numbers and grabs. They are individually manageable with melee weapons if you have space — don't waste precious ammo on them. Keep distance, use efficient melee, and treat every contact as a noise event: one zombie can quickly cascade into a horde.

Runners & Shamblers

Runners close distance fast and disrupt your formation. Call them out, interrupt their approach with a shove, and deny a clean lunge. A Runner inside the team forces several Responders to turn away from the main horde — handle them before slower zombies.

Shamblers are the priority-breakers: they scream to summon more zombies and release infection gas that can infect Responders and raise nearby zombies. Focus the Shambler before repeated screams escalate the encounter, then move out of the gas cloud instead of fighting inside it.

Prime Zombies & Prime Runners

Prime is a state that raises a zombie's health and damage — a durable, high-damage priority target. The 1.0 balance reference lists Prime at 130 health, compared with 100 for a normal zombie and 70 for a Shambler.

Mark the target and concentrate fire rather than letting teammates trade hits with it individually. Prime Runners exist too — when Prime variants appear during a heavy push, focus them, keep them away from speakers or objective points, and use high-damage weapons.

Screamers — Kill Them First

Screamers are the game's alarm system. They look like spindly, hunched figures, and when they scream they summon a large number of additional zombies — turning a manageable fight into a crisis.

Screamers always change your priorities. Kill them before they complete the scream. A ranged weapon is the safest answer, though an experienced melee player can eliminate one quietly. Never leave a Screamer alive while the team is already fighting the horde in front of you.

Armored Variants (Firefighter, Riot Police)

Armored zombies interfere with simple headshot plans:

• Firefighters wear a helmet and carry a reactive gas canister. When triggered, it gives a short visual warning before an air explosion that knocks down nearby zombies without dealing damage. Shoot it from a distance when the knockdown creates a useful opening — never stand beside the canister once the warning starts.
• Riot Police add body armor and may carry a shield. Directional melee can reach around shield coverage, while firearms need sufficient caliber penetration. The head and legs become much more attractive targets.
• Construction workers wear helmet protection — change your attack angle or tool instead of relying on an exposed headshot.

National Guard variants have high damage resistance and resist knockdowns — treat them as priority targets, not ordinary zombies with more health.

Higher difficulties change horde composition and density. Nightmare includes more special types, Runners and Prime zombies, so learn target recognition before the group is fully engaged.
