No More Room in Hell: Survival Guide

A practical survival guide to No More Room in Hell: game modes, infection, weapons and ammo, teamwork, the new 1.15 networking update, and how the original compares to No More Room in Hell 2.

Researched September 2026 — current as of the 1.15 Networking Update (September 1, 2026). Live games change; check the linked sources if something differs.

What's New (as of September 2026)

• Update 1.15, the "Networking Update" (September 1, 2026). This is a Source engine upgrade with:
• 64-bit support. 64-bit binaries launch automatically on 64-bit systems.
• Steam Networking. Hosting no longer needs port forwarding.
• A borderless window option, UI scaling for high-resolution screens, and a native-resolution launch by default instead of 640x480.
• Bicubic lightmaps and radial fog from Half-Life 2's 20th Anniversary Update, plus a Vulkan renderer (the default on Linux).
• Many fixes to movement prediction and networking, which should mean less rubber-banding.
• Update 1.14.2 (April 2025) added better offline solo play. Set max players to 1 in the Create Server dialog.
• Update 1.14 (October 2024) added the Shoreline map.
• No More Room in Hell 2 (Torn Banner Studios) left Early Access and hit 1.0 in August 2026. It is a separate paid game. The original is still free and still getting updates.

Quick Start

• Aim for the head. Zombies only go down for good with head damage. There is no crosshair, so aim down the sights.
• Ammo is scarce. Use melee on single zombies and save bullets for runners and emergencies.
• Stick with your team. Voice and text chat only reach players nearby. Walkie-talkies let you talk across the map.
• Watch for infection. A bite or grab can infect you. Pills (Phalanx) slow the infection down and gene therapy cures it.
• Manage your stamina. Sprinting and swinging drain it. Getting caught out of breath in a crowd is how most players die.
• Keep an eye on weight. Carrying too much slows you down. Share the heavy stuff.
• Shove to make space. A shove pushes zombies back so you can reposition or finish them.
• Learn the objectives. Objective maps have randomized tasks and routes, so read the objective text every time.
• Offline practice is easy now. Set max players to 1 when you create a server.

Game Modes

Mode | Goal | Key tips

Objective | Complete the map's objective chain and reach extraction | Objectives, items and routes are randomized. Stay together and share keys and tools

Survival | Defend your area's safe zones against waves until rescue arrives | Supply drops come in between waves. If all safe zones lose their health, the rescue fails

In Survival, respawns depend on the mode's rules: at the start of a wave, or instantly based on points. On Objective maps, you can often respawn at checkpoints on easier difficulties.

Zombies

Type | Behavior | How to handle it

Shamblers | Slow walkers, dangerous in groups | Melee headshots. Keep moving, never let them surround you

Runners | Fast and aggressive | Shoot them when they come around corners. Back into a corridor

Kid zombies | Small targets | Easy to miss, so aim lower and take your time

The game uses crowds and noise. Gunshots draw zombies, so a single shot can pull in more than it kills.

Infection

• Zombies can grab and bite. Bites can infect you, and the chance goes up the lower your health is.
• The screen edges darken and warp as the infection gets worse.
• Phalanx pills slow the infection. Gene therapy cures it and makes you immune.
• If the infection runs out, you turn into a zombie and attack your team.
• Tell your team if you are infected. The store page calls deciding whether to warn them one of the game's big choices. The team-friendly move is always to speak up and hand off your gear before you turn.

Weapons and Items

Firearms

The store page lists 30+ weapons across melee and firearms. Wikipedia counts up to 18 firearms, from the small .22 Target Pistol up through shotguns and rifles. Ammo is split into separate types, so check what your gun uses before you pick up ammo.

Category | Use

Handguns | Light and quick. Good backup

Shotguns | Crowd clearing up close. Heavy ammo

Rifles | Precise headshots at range. Scarce ammo

Specialty (bow, flare gun, explosives) | Situational. Save them for big moments

Melee

The developers made melee a real option:

• Blunt weapons such as bats and sledgehammers can stagger and knock zombies back.
• Edged weapons such as fire axes, machetes and knives kill quickly with good placement.
• Power tools such as the chainsaw are fast but loud and use fuel.

Tools and medical items

Item | Use

Bandages | Stop bleeding

First aid kit | Heals a large amount

Phalanx pills | Slows infection

Gene therapy | Cures infection and gives immunity

Walkie-talkie | Talk to teammates across the map

Flashlight or light sources | Essential in dark maps

Barricade hammer and boards | Board up doors and windows (useful in Survival)

Grenades and TNT | Crowd clearing. Watch out for teammates

Teamwork

• Use proximity voice on purpose. If you move away from the group, nobody can hear your calls.
• Share ammo and medicine. Give ammo to whoever carries the gun that uses it.
• Assign a light carrier on dark maps.
• Call out infected players early so the team can plan.
• Recover gear. When someone dies, their loot stays behind. Collect it and pass it along.

Your First Objective Round, Step by Step

• Spawn and check your hands. You often start with little or nothing. Your fists or flashlight will not last, so the first job is finding a melee weapon.
• Loot the first building together. Split rooms between players, but stay within shouting distance, because proximity voice fades quickly.
• Read the objective text in the HUD or objective menu. It tells you what to find, such as a key, a fuse or a person, and those locations can change between rounds.
• Spread the guns out. Give firearms to the players with the best aim and keep melee users up front to handle single zombies quietly.
• Move as a group between objectives. Clear corners, check behind you, and do not sprint ahead of the team.
• Before extraction, top up health, share the last ammo and make sure nobody is secretly infected.
• At extraction, hold a defensible spot until the rescue arrives. Players who wander off at the end are the classic last-minute death.

Difficulty and Server Settings

• Servers pick a difficulty and can use rulesets, challenges and mutators that change zombie counts, runner frequency and resources. Check the server name and description before you join.
• Harder settings mean more runners, fewer supplies and stricter respawn rules. Learn the maps on easier servers first.
• Community servers often run custom maps from the Workshop, and the game's modding tools keep improving (1.14.x added new VScript and mapper features).

Common Mistakes to Avoid

• Firing at every zombie. Noise attracts more and ammo runs out.
• Sprinting into crowds. You run out of stamina right where you do not want to be.
• Hiding an infection. Your team loses someone either way, and it is worse if you turn in the middle of the group.
• Wandering off alone. Proximity chat means no one knows you are in trouble.
• Carrying too much. You get slowed down.
• Ignoring objective text. Randomized objectives mean last round's route might not work.

Advanced Tips

• Shove, then strike. Push a zombie back, then land a clean melee headshot.
• Use chokepoints. Doorways and hallways turn crowds into single-file lines.
• Pre-assign ammo types. Everyone should carry different guns so ammo is not wasted.
• Explosives on hordes only. Save grenades and TNT for real hordes. Friendly fire is real.
• Survival waves: Reinforce the most-attacked safe zones first. Board up entrances between waves.
• Hosting in 1.15: Steam Networking means friends can join your server without you setting up port forwarding.
• Solo practice: Set max players to 1 in the Create Server dialog (since 1.14.2) to learn maps offline.
