How Weapon Mods Work

Weapon mods can dramatically improve the performance of your gear in Cyberpunk 2077.

Some increase critical hit potential, others boost stealth damage, while a few completely transform how certain weapon types perform.

Choosing the right mod is often just as important as choosing the weapon itself.


Wallpuncher

Why It's Great

Wallpuncher is arguably the strongest weapon mod in the game for Tech weapon users.

Benefits include:

  • Doubles charge capacity
  • Greatly increases charged shot damage
  • Adds 100 Armor Penetration
  • No increase to charge time

For players using Tech weapons, the damage increase is enormous.

How To Get It

Complete:

The Spider And The Fly

during Phantom Liberty.

After defeating the Militech Chimera, obtain the Active Chimera Core and use it to craft Wallpuncher.

Keep in mind that the Chimera Core can only be used once.


Trajectory Analysis

Why It's Great

This legendary Kiroshi Optics mod provides:

  • 25% additional headshot damage

For sniper builds and precision shooters, this is one of the best damage increases available.

How To Get It

Purchase it from:

Viktor Vektor

in Little China.

Although expensive, it's one of the strongest upgrades for players who consistently land headshots.


Vendetta

Why It's Great

Vendetta increases:

  • Headshot damage by 20%

The bonus applies to virtually every ranged weapon and stacks well with other headshot-focused upgrades.

How To Get It

Look for a briefcase in an alley within:

The Glen

in Heywood.

The mod can be found among the aftermath of a gang conflict.


Penetrator

Why It's Great

Penetrator increases:

  • Critical hit chance by up to 7%

For players chasing high critical hit builds, this is one of the most valuable weapon mods available.

How To Get It

The crafting blueprint can be found in:

Wellsprings

between:

  • Berkley & Bay
  • Palms View Plaza

Epic versions may also be purchased from various vendors throughout Night City.


Pacifier

Why It's Great

Pacifier increases:

  • Critical hit damage by 14%

Once your build already has a strong critical hit chance, Pacifier becomes one of the best ways to increase overall damage output.

How To Get It

Purchase the blueprint from the gun store in:

Western Wellsprings

Then craft the mod yourself.


XC-10 Alecto

Why It's Great

The best suppressor for stealth builds.

Benefits include:

  • 2.5x stealth damage multiplier
  • Functions as a silencer
  • Only reduces combat damage by 15%

Compared to other silencers, the damage penalty is extremely small.

How To Get It

Complete an Assault In Progress activity in:

Rancho Coronado

within Santo Domingo.

The mod can be found inside a suitcase near the event location.

Step-by-Step

  1. Decide which weapon type you use most.
  2. Identify the mod that best supports that playstyle.
  3. Acquire the blueprint or mod location.
  4. Craft or purchase the upgrade.
  5. Install the mod on compatible equipment.
  6. Continue optimizing your build around the mod's strengths.

Best Strategy

  • Match your weapon mods to your build instead of equipping them randomly.
  • Prioritize critical hit mods for gunslinger builds.
  • Focus on headshot bonuses if using sniper rifles or precision weapons.
  • Save the Chimera Core for Wallpuncher if you're running Tech weapons.
  • Combine stealth mods with silenced weapons for maximum effectiveness.

Tips

  • Wallpuncher is often considered the strongest single weapon mod added by Phantom Liberty.
  • Critical hit builds benefit greatly from combining Penetrator and Pacifier.
  • Trajectory Analysis can dramatically increase sniper effectiveness.
  • Stealth players should prioritize XC-10 Alecto as soon as possible.
  • Not every legendary mod is equally useful. Build synergy matters more than rarity.
