The Breach Cutter releases directional blasts of sonically-charged plasma powerful enough to deal with most any alien in your path. Originally a mining tool, it's now been frequency-tuned to crack open flesh and bone rather than the sediment deposits it was designed for - often with quite spectacular results!
— Weapon Description

The Breach Cutter is an unlockable secondary weapon used by the Engineer. Once used as a mining tool, it has since been converted into a weapon. Batteries are loaded into the top of the weapon which fire horizontally expanding plasma blades, focused by the barrel on the front of the weapon. The Breach Cutter is one of the largest weapons in the game.

When fired the plasma blade will expand and travel as a long purple line, then close up a second and a half later. The plasma blades deal damage for every tick they come into contact with an enemy.

The plasma blades are infinitely piercing and can cleave through as many enemies as they like, as well as passing through any terrain without damage losses, allowing the user to hit targets behind walls.


There are five tiers of modifications and each tier has two to three upgrades. Only one modification can be equipped per tier.

Stats Breakdown[]

Understanding the Weapon[]

  • Damage is the total amount of damage that is dealt over the course of one second against any enemy that is within contact of the beam.
    • Damage (per tick): 11.5
    • Damage type: 50% Electric / 50% Fire
    • Tick interval: 0.02s
    • Friendly Fire Modifier: x0.15
  • Projectile Lifetime is the amount of time that the beam is able to travel before dissipating.
    • Projectile velocity: 10m/s
  • Creatures hit by the line have a x0.3 movement penalty.
  • There is a bonus of 50 Fire damage upon first contact with a creature (does not happen when Spinning Death OC is equipped), with a x0.1 friendly fire modifier.
  • The Breach Cutter's damage is unique in that while it is spread out over an Area, ignores armor, and is unaffected by the Frozen status it is still able to deal increased damage to enemy Weakpoints.

Unique Modifications[]

Explosive Goodbye[]

Icon Upgrade Explosion

Explosive Goodbye causes the Breach Cutter's shots to explode at the end of their life span, dealing a maximum of 40 damage. The explosion occurs once the beam has fully retracted into its epicenter or can be manually triggered by firing again (only after 0.4s of the line leaving the weapon), which will leave a plasma field that periodically damages any enemy that comes into contact and slows them (8 Fire Damage every 0.2-0.25s, and x0.8 Movement speed).

  • Damage: 40 Explosive
  • Radius: 3.5m
  • Maximum Damage Radius: 2.5m
  • Minimum Damage: 50%
  • Friendly Fire Modifier: x0.2
  • Arming Delay: 0.4s
  • Field Damage (per tick): 8 Fire
  • Field Tick Rate: 0.2-0.25s
  • Movement Speed: x0.8
  • Field Duration: 4s

Plasma Trail[]

Icon Upgrade Area Damage

Plasma Trail causes the Breach Cutter's shot to temporarily leave a trail of plasma as it travels along in any direction, which will periodically damage any enemy that comes into contact.

  • Damage: 5 Fire
  • Interval: 0.2 - 0.3 s
  • Duration: 4 seconds default duration, with an additional +0.6 seconds added only one time if any enemies either enter or leave the field.

Triple Split Line[]

Icon Upgrade Area

Triple Split Line causes two extra beams to appear in parallel with every shot. Triple Split Line itself will not cause more damage to be dealt, however will increase the surface area for contact of each shot. Increased surface area means each shot can potentially deal the maximum number of damage because of how long the beam stays in contact with each creature. Increased surface area also means more contact for the shot to destroy armor.

Unique Overclocks[]

Roll Control[]

Frame Overclock Clean
Icon Overclock Spinning Linecutter

Roll Control is a Clean Overclock

Return To Sender[]

Frame Overclock Balanced
Icon Overclock ForthAndBack Linecutter

Return To Sender is a Balanced Overclock

This Overclock causes the beam to return to the point it has been shot from.

When you hold down the trigger, the plasma beam will emerge from the breach cutter like normal. When you release the trigger, the beam will reverse. This is very useful because you can deal twice the damage with one beam. If you want to spam fire or fire the weapon normally, you have to tap the trigger. This will cause the beam to continue its path until it breaks, like without the Overclock.

High Voltage Crossover[]

Frame Overclock Balanced
Icon Upgrade Electricity

High Voltage Crossover is a Balanced Overclock

  • Electrocution Chance: 100% (4 Electric damage every 0.25s)
  • Duration: 4s

Spinning Death[]

Frame Overclock Unstable
Icon Upgrade Special

Spinning Death is an Unstable Overclock

This unstable overclock causes the plasma beam to spin on its y axis.

When you shoot, the plasma beam emerges and moves at 5% of the default speed (0.5m/s instead of 10 m/s). Then the beam starts spinning around its y axis very quickly and deals moderate amounts of damage to whatever is in it. The first impact bonus damage is also reduced to 0.


Frame Overclock Unstable
Icon Upgrade Heat

Inferno is an Unstable Overclock
Apart from doing damage, the line will also deal Heat every second, the Heat is 90% of the DPS value.
In addition to the usual 50 Fire damage on first contact with a creature, the line will deal 75 Heat.
The creatures touched by the line have a hidden DoT applied that deals 7 Heat and 7 Fire damage every 0.5 seconds for 5 seconds.

  • According to the Breach Cutter's description, it was originally a mining tool used to clear sediment deposits before eventually being converted into a weapon. Mission Control remarks upon this when the weapon is unlocked, joking that Planet Hoxxes "sure does breed innovation".
  • The Breach Cutter's internal name is "Line Cutter", its name and design being a reference to two weapons from the Dead Space franchise: the Plasma Cutter and the Line Gun respectively.
