Firearms in No More Room in Hell 2: A Complete Armory Guide

No More Room in Hell 2 (NMRiH2) is not a game where you are handed a full auto rifle and a thousand rounds before you leave the spawn. It is a cooperative, survival-horror zombie FPS that thrives on tension, limited resources, and every single bullet counting. Set in the drab, decaying world of the Half-Life universe, the game treats firearms not as toys but as lifelines. Understanding the weapon system—from the humble 9mm pistol to the heavy-duty shotgun—can be the difference between clearing a safehouse and becoming another graveyard statistic.

This guide covers every firearm class currently represented in NMRiH2, the mechanics behind accuracy and stances, ammunition scarcity, and a detailed comparison table to help you decide which guns to grab when the swarm starts to press.

1. Overview: Why Firearms Matter in NMRiH2

In NMRiH2, zombies are not the fast, sprinting infected from Left 4 Dead. They are shambling, group-based, and relentless. Firearms are your primary tool for medium-to-long-range engagement, crowd control, and accidentally drawing every walker in the building to your position. The game’s sound propagation system punishes carelessness—a single unsuppressed pistol shot can bring a horde down on your squad.

Unlike many zombie co-op shooters, there is no reticle, no hit-marker by default, and no magical reserves of ammunition. You must manage your magazine, your stance, and your inventory. Firearms also suffer from weapon condition and jamming, especially when you find worn-down rifles in closet corners. In short, firearms are vital, but every tactical decision with them has weight.

The key design philosophy of NMRiH2’s gunplay is this: the gun is a fallback, not a dependency. Players are encouraged to conserve ammo and use melee weapons for isolated walkers, reserving gunfire for emergencies, sprinters (if any appear), and bosses. Still, no survivor can survive long without a good firearm, so it pays to know your tools.

2. Handguns and Sidearms

Sidearms are the most common firearms in NMRiH2. They are lightweight, relatively easy to conceal, and often the first functional ranged weapon you will find in police stations, houses, and military outposts. They are not ideal primary weapons for late-game missions, but they can absolutely save your life when you are pinned in a narrow corridor and your long arm is empty.

Pistols

The pistol category includes all semi-automatic handguns that chamber a magazine-fed cartridge. The most common early-game pistol is the 9mm Glock or M9 Beretta style sidearm. These have moderate magazine capacity, light recoil, and are effective against standard zombies when shot in the head.

A headshot from a 9mm pistol will nearly always take down a basic walker, but it may take multiple rounds if the zombie is armored or doesn’t have a clean skull strike. Because there is no crosshair, you will need to use the "iron sights" or "hip-fire" stance carefully. Pistols are excellent back-up weapons because they share ammunition with some SMGs, and the magazine is small enough to make every bullet a thoughtful choice.

Revolvers

Revolvers are the heavy hitters of the sidearm category. Usually chambered in .357 Magnum or .44 Magnum, these weapons pack a punch that can drop a walker in one shot, regardless of where you hit. The trade-off is obvious: six rounds, long reload time, and a hell of a weight in your hand.

The S&W 686 style revolver is favored by players who want guaranteed kills without needing to find a rifle. It is also useful for breaking through hordes in tight spaces because the penetrating power of a .357 round can pass through one zombie’s skull and hit another behind it. However, revolvers are not meant for suppression. Each pull of the trigger is a moral contract with the zombie that it will die or you will be swarmed.

3. Submachine Guns and Automatic Weapons

Submachine guns (SMGs) are the bridge between pistols and rifles. They use pistol-caliber ammunition, but they fire automatically, giving you a burst of lead when you need to clear out a room with speed. In NMRiH2, SMGs are extremely rare early on and often near police/military areas.

The iconic H&K MP5 is a perfect example. It is chambered in 9mm, making it versatile with your sidearm ammunition. It has manageable recoil, a decent rate of fire, and accepts magazine extents and suppressors. SMGs are the best choice for "active reload" situations—you can keep moving while emptying a magazine into a crowd, and the lightweight nature allows you to keep a backpack full of loot and still sprint.

Automatic weapons like the MP5K or Uzi have a higher volume of fire, but their accuracy drops sharply without a stock. As a rule, use SMGs for close-quarters battles, when searching buildings, and when you know you can resupply from a police crate. If you are using an SMG as a primary for the entire mission, you will probably run out of 9mm very quickly.

One caution: automatic fire is a siren. In NMRiH2, unsuppressed automatic gunfire can draw zombies from unreasonably far away. A full burst may clear a room, but it also ensures the next five minutes will be spent fighting every walker in the alley network.

4. Shotgun Varieties and Their Uses

The shotgun is the undisputed king of close-range zombie elimination. There is something extremely satisfying about racking a pump action and clearing a corridor in one shell. However, NMRiH2 does not treat shotguns as a "point and delete" weapon. You must still account for the spread, range, and the preciousness of shells.

Pump-Action Shotguns

The Remington 870 and Mossberg 500 style pump-actions are the workhorses. They hold 5-8 shells, load one at a time, and have a punishing melee animation if you have to buttstroke a zombie that got too close. Their accuracy is tight enough for close-range headshots, but the pellet spread makes them useless past about 10 meters. A single close-range shell to a zombie’s head will often sever or destroy the skull—guaranteeing an instant kill.

Because shells are bulky and relatively scarce, pump-action shotguns are best for "door control" situations. If you are defending a barricade with a narrow entrance, a shotgun can hold the line better than any rifle, because one shot can destroy multiple bodies at once.

Semi-Auto and Breaching Shotguns

Less common, but deadlier, are semi-automatic shotguns like the SPAS-12 or M1014. These offer a similar shot profile with a faster follow-up capability. They consume shells more quickly, but they can suppress a horde faster and are essential during boss sequences or "objective defense" segments where zombies spawn in waves.

The main drawback of semi-auto shotguns is the power-to-ammo ratio. With a pump-action, missing a shot is a learning opportunity. With a semi-auto, missing a shot is a lottery ticket to being overloaded by walkers. Still, for experienced players, a semi-auto shotgun is arguably the most versatile close-quarters weapon in the game.

5. Rifle Classifications

Rifles are the precision instruments of NMRiH2. They are powerful, accurate, and consume relatively rare rifle ammunition. There are several distinct rifle subcategories based on their action and role.

Bolt-Action Hunting Rifles

These are the stereotypical "hunting rifle" found in farmhouses and sporting goods stores. Chambered in .308 Winchester or 7.62x54R, they use scoped or iron-sight optics. Bolts are slow to cycle but deliver massive damage—one well-placed shot to the torso can put down a normal zombie, and a headshot will instantly drop almost everything in the game, including armored walkers.

Because of their low fire rate, bolt-action rifles are best used from elevated static positions. They are not ideal for clearing houses, but they are exceptional for "taking out the big ones" and engaging from a safe distance. If you have a scoped bolt-action, you can also tag the head of a raider (if human enemies appear in certain modes) or send a message to the zombie horde before it reaches your group.

Semi-Auto Civilian Rifles

Weapons like the M1 Garand or SKS combine reasonable magazine capacity with respectable stopping power. They are chambered in .30-06 or 7.62x39, depending on the model, and offer rapid follow-up shots without burning through ammunition. These are arguably the most reliable "scavenger" rifles because they are commonly found in civilian homes, gun safes, and hunter cabins.

Assault and Battle Rifles

The military-grade rifles—M16A2, M4A1, AKM, G3—are an endgame dream. They offer select-fire capability (semi, burst, fully automatic), larger magazines, and the ability to suppress or equip with advanced optics. They use 5.56mm NATO or 7.62x39mm ammo. These rifles are the only weapons that allow you to engage a horde from mid-range and still win. But they are heavy.

An important distinction: in NMRiH2, an "assault rifle" is not just a rifle used for an assault. It is a rifle that has a detachable box magazine, selective fire, and a pistol grip. Due to the realism factor, these weapons are far rarer early in a match. They often spawn in police armories, military checkpoints, or locked crates. If you find one, treat it like a treasure and be very mindful of ammo expenditure.

6. Ammunition Scarcity and Conservation

No discussion of firearms in NMRiH2 is complete without an acknowledgment of ammunition scarcity. The game is not a sandbox with infinite respawning pick-ups. Every bullet is a finite resource, and once it is fired, it is gone. Ammo boxes can be found in police stations, military crates, and residential safes, but they give you only a handful of rounds. The best strategy is to treat every bullet as if you will never find another one.

Ammunition is categorized by type:

• 9mm: common, used by pistols and SMGs.
• .45 ACP: less common, used by some pistols and SMGs.
• .357 Magnum / .44 Magnum: rare, for revolvers.
• 12 Gauge: medium, for shotguns.
• 5.56mm / .223: military-grade, for M16, M4, and similar rifles.
• 7.62x39mm: common for AK-pattern rifles.
• .308 / 30-06: for bolt-action and battle rifles.

To conserve ammunition, the game mechanics encourage smart reloading and weapon switching. You can "drop" a half-empty magazine? Actually, in NMRiH2, magazine management is crucial. If you reload before emptying a mag, you keep the partial mag in your inventory. That partial mag can be reinserted later. But if you press "reload" during an empty mag, the used magazine is gone. Learning to keep a visible "ammo count" is essential.

Also, do not fire what you do not need. A zombie alone in a room can be dispatched with a melee weapon. Only fire when the zombie is part of a group, or when you are being chased and cannot afford to turn around. Sound is your enemy. Gunshots attract more zombies, which means you will have to use more bullets, which attracts more zombies—this is the circle of death in NMRiH2.

7. Weapon Attachments and Modifications

NMRiH2 includes a limited but impactful attachment system. Many weapons spawn with no attachments, but you can find:

• Suppressors: Reduces muzzle blast and dramatically lowers the chance of alerting zombies, but slightly reduces damage and adds to weapon weight.
• Flashlights: Essential for dark levels; attach to a rail to free up your hand and avoid the clunky "light + gun glitch."
• Red Dot / Holo Sights: Improves target acquisition and reduces effective sway without zoom.
• Scopes: Optical zooms for rifles; make long-range headshots possible but hamper close-quarters awareness.
• Extended Magazines: Raise ammo capacity (often from 30 to 45/50) but increase reload time and overall weapon weight.
• Foregrips: Reduce horizontal sway, enabling more accurate automatic fire.

Modifications are found as loose items in the world or as pre-attached parts on military rifles. However, the attachment system in NMRiH2 is not as arcade-friendly as in other shooters. You cannot carry a universal toolbox and snap a laser onto any gun. Instead, you need the correct mounting hardware, which is a rare find. For example, a Glock may have a underbarrel rail but not a Picatinny rail for a foregrip. Attaching a suppressor to a rifle without a threaded barrel is impossible.

If you find a suppressor, consider using a semi-automatic rifle rather than an SMG. A suppressed rifle can kill from medium range without every zombie in the county hearing you. However, suppressors do not make you completely silent. The shot is still audible within a reduced radius.

8. Firing Stances and Accuracy Mechanics

NMRiH2 is renowned for its realistic attitude towards marksmanship. You cannot simply hold a high-power rifle at eye level and have the crosshair remain steady. There are multiple stances to consider, each with its own impact on recoil and accuracy:

Hip-Fire Stance

The default stance when you are not pressing the "aim" key. Characters hold the weapon at their hip or shoulder-slung. Hip-fire is inaccurate. Bullets will randomly deviate from the center of the screen, and at close range, the weapon may actually point slightly off-center due to animation sway. Hip-fire is best used in emergency situations when a zombie is right in front of your face and you cannot raise the sights in time. The only upside is that your movement speed remains "walk" rather than "crawl."

Aimed/Shouldering Stance

Pressing the right mouse button (if you have the conventional setup) brings the weapon up to your shoulder. This is mandatory for any precise shot. Once aimed, your character’s breathing and stamina start to affect the sight picture. If you are exhausted from carrying a heavy load, the sight will sway in a lazy circle. Holding your breath (usually by pressing a key like Shift or L-Alt) temporarily steadies the weapon, but your stamina drains fast.

Crouched Stance

Crouching reduces your profile and increases stability of the weapon. Crouching with your weapon aimed creates a much more stable shooting platform, especially for long-range shots. The trade-off is speed; you are a stationary target. For bolt-action rifles and scoped weapons, crouching is almost mandatory when shooting at distances beyond 50 meters.

Prone Stance

NMRiH2 includes a prone stance (if the server enables it). Prone is the most accurate way to fire a rifle, with almost no sway. However, you are extremely vulnerable to zombies and cannot see threats coming from behind. The prone stance is ideal for last-stand situations, when the horde is coming down a single alley and you have a high-capacity rifle.
