In CQB Hell, a tactical PvE Roblox shooter developed by FREEDOM TO KILLART STUDIOS, weapon attachments allow players to modify handling, recoil damping, vision, and ballistics during a run. Operators customize their firearms mid-mission by locating stationary workbenches known as Weapon Attachment Machines across operational sectors.
Not all firearms support every modification, making it vital to understand which attachments and specialized ammunition types fit your weapon loadout before entering high-threat rooms.
Weapon Attachment Machine Categories
The Weapon Attachment Machine (also referred to as the Weapon Upgrader) functions as a dedicated workbench where operators alter firearm characteristics. Upgrades are organized into five primary categories:
- Sights & Optics: Improve target acquisition accuracy, enhance sight picture visibility, and provide zoom magnification when aiming down sights.
- Silencers & Muzzles: Dampen weapon firing noise and extend bullet range.
- Underbarrel: Grip attachments and bipods designed to significantly reduce both vertical and horizontal weapon recoil.
- Other: Tactical utility modules, such as tactical flashlights to illuminate pitch-black areas and laser sights to enhance hip-fire accuracy.
- Ammo Info: Displays compatible calibers and allows operators to switch to specialized ammo types tailored to unarmored or heavily armored targets.
Ammunition Types and Combat Modifiers
Specialized ammo can be loaded at attachment stations to adapt weapons to specific enemy profiles. Each ammo modification carries distinct stat trade-offs:
| Ammo Type | Tactical Breakdown |
|---|---|
| Light Ammo | Reduces overall weapon recoil and increases mobility, but scales down base kinetic damage. |
| Armor-Piercing (AP) Ammo | Built with high-penetration ballistics to bypass heavy NPC body armor and negate armor integrity. |
| Heavy Ammo | Delivers high stopping power and amplifies base damage output, but increases vertical recoil. |
| High Grade Ammo | Increases muzzle velocity by 30% and completely removes weapon jam chances. |
| Incendiary Ammo | Combines kinetic impact with a thermal payload that ignites targets, applying damage-over-time (DoT) and area disruption. |
| Explosive Ammo | Deals extreme blast damage in a small radius, but increases recoil, spread, and jam chance while lowering velocity and fire rate. |
| Blanks | Zeroes out kinetic impact damage completely; primarily utilized for training or signaling. |
Weapon Compatibility and Attachment Limits
Firearms in CQB Hell feature fixed customization slots based on their class and weapon frame. Certain compact or makeshift weapons have limited compatibility, while standard rifles accommodate wider modularity.
- GV-15: A primary semi-automatic rifle that accepts Optics for close-range alignment, Underbarrel grips for sustained recoil control, and Ammo conversions.
- OBREZ: A sawed-off bolt-action rifle in the tertiary slot. It only accepts Ammo category modifications (such as Light, Standard, or AP rounds) and cannot mount forward grips or muzzle attachments.
- AKM with no recoil spring: A primary bolt-action conversion of the AK platform that supports Ammo category conversions, but lacks standard automatic furniture.
In addition to workbench modifications, players navigating dark sectors can pair weapon flashlights with looted Chemlights or Night Vision Goggles (NVGs) dropped by enemies to maintain visibility without giving away positions.
Weapon Jamming and the Gun Cleaning Kit
Weapon malfunction is an active hazard in CQB Hell, particularly when firing sustained bursts or loading volatile calibers like Explosive ammo. Jams force operators into reload or clearing animations mid-combat.
Operators can mitigate this risk by looting a Gun cleaning kit, which drops from defeated enemies, Sawmill conveyor belts, or the Random Dispenser:
- Jam Immunity: Temporarily removes weapon jams across any ammunition type for up to 100 rounds.
- Condition Check: Players can inspect their weapon to view the remaining percentage of the "Cleaned gun buff."
- No Stacking: Using a second cleaning kit does not stack total rounds; it only refreshes the 100-round buff back to full.
- G18 Fire Selector: Applying a cleaning kit to a G18 handgun unlocks the ability to toggle between semi-automatic and full-automatic fire.
Frequently Asked Questions
Where do you find Weapon Attachment Machines in CQB Hell?
Weapon Attachment Machines spawn as interactive workbenches inside operational sectors along your route, appearing between cleared combat rooms and safe transition zones.
Does Armor-Piercing (AP) ammo lower your damage?
AP ammo does not lower penetration damage against armored foes. It is specifically designed to negate heavy NPC armor integrity, though against unarmored targets it may deal slightly different damage values compared to pure Heavy ammo.
Can every firearm use silencers and underbarrel grips?
No. Attachment availability depends strictly on the weapon. Stripped-down or makeshift weapons, such as the OBREZ sawed-off rifle, only allow ammunition swaps, whereas full-sized platforms like the GV-15 support optics, underbarrels, and ammo types.
