How to Attach Weapon Attachments in No More Room in Hell 2

How do you equip weapon attachments in No More Room in Hell 2? Check compatibility, inventory steps, and what to do when an attachment will not equip.

What You Need to Know About Attaching Attachments

Attaching attachments in No More Room in Hell 2 is a quick process once you know the correct button and the compatibility rules. This guide walks you through the exact steps to attach optics, suppressors, and rail attachments to your weapons, and what to do when the game won't let you.

Direct Outcome

By the end of this guide, you'll be able to attach any compatible attachment to your equipped weapon using the Y key, identify why an attachment might not fit, and apply advanced tips to get the most out of your loadout.

Prerequisites

Before you can attach an attachment, make sure you have the following:

  • An attachment item in your inventory. These drop during runs and can be found in weapon lockers, on tables, or from fallen survivors.
  • A compatible weapon equipped. Not every attachment fits every gun.
  • The game updated to a version that includes the weapon attachments system. Attachments were introduced in a major update, so if you don't see them, verify your game is current.

How to Attach Attachments: Step-by-Step

Follow these steps to attach an attachment to your weapon:

  1. Equip the weapon you want to modify. Your active weapon is the one that will receive the attachment.

  2. Open your inventory by pressing the inventory key (default: Tab).

  3. Locate the attachment you want to use. It will appear as an item icon in your inventory grid.

  4. Press the Y key while the attachment is selected or while your weapon is equipped. This is the default keybind for attaching items to your current weapon.

    Community report: Players on the Steam forums confirm that pressing Y is the correct way to attach items. If the attachment doesn't attach, it means the attachment is not compatible with your current weapon.

  5. Confirm the attachment is equipped. Your weapon model should visually change, and the attachment's icon should no longer be in your inventory.

That's it. The process takes seconds once you know the button.

Common Mistakes and How to Fix Them

Mistake 1: Pressing the Wrong Key

Many players try to attach attachments through the inventory menu by dragging or clicking. In No More Room in Hell 2, the Y key is the dedicated attach button.

Fix: Equip your weapon, then press Y. If nothing happens, make sure you have the weapon actively equipped (not holstered) and that you're not in a menu that blocks inputs.

Mistake 2: Incompatible Attachment and Weapon

The most common reason an attachment won't attach is incompatibility. A pistol suppressor will not fit a rifle, and a rail attachment won't mount on a weapon without a rail.

Fix: Check what type of attachment you have. The game has three main attachment types:

Attachment TypeExamplesTypical Compatible Weapons
OpticsRed dot sights, scopesRifles, SMGs, some pistols
SuppressorsPistol suppressors, rifle suppressorsPistols, SMGs, rifles (must match caliber/size)
Rail attachmentsFlashlights, grips, lasersWeapons with accessory rails

If you're unsure, try the attachment on a different weapon. If it still won't attach, it's likely an issue with the attachment itself or a bug.

Mistake 3: Attachment Is Already Used or Consumed

Some attachments are single-use. If you've already attached it to another weapon, you won't have it in your inventory anymore.

Fix: Check your inventory for the attachment. If it's gone, it's already on another weapon. You can remove it from that weapon (if the game allows) or find another one.

Mistake 4: Game Version or Bugs

Occasionally, bugs prevent attachments from working. The official update notes mention fixes to attachment-related issues, including blood decals appearing on attachments incorrectly.

Fix: Ensure your game is updated to the latest version. If you're on the latest version and still experience issues, restart the game or verify game files through Steam.

Advanced Tips for Attachments

Once you've mastered the basics, use these tips to get more out of the attachment system:

  • Match attachment types to your role. If you're the team's point man, a flashlight rail attachment helps you clear dark areas. If you're a designated marksman, prioritize optics.
  • Suppressors reduce noise but may not be silent. In No More Room in Hell 2, zombies are attracted to sound. A suppressor can help you avoid drawing a horde, but it's not a guarantee of stealth.
  • Check weapon stats before attaching. Some attachments may alter handling, recoil, or aim speed. Experiment with different combinations to find what works for your playstyle.
  • Keep an eye out for rare attachments. Higher-difficulty runs and special loot spawns may offer attachments you won't find in normal playthroughs.
