More precise than an SMG, with the stopping power of a small shotgun, the BRT (or "Burt", as it's sometimes called) is highly prized among collectors and connoisseurs alike.
— Item Description

The BRT7 Burst Fire Gun (also known as the "BRT") is the Gunner's alternative secondary weapon. It is a handgun with a long barrel and a slender profile. The weapon's magazines are stored internally, and the port is accessed by pulling the knob above the weapon's handle to reveal it.

The Burt fires three bullets in a rapid burst with one pull of the trigger. One burst of bullets all follow the same spread pattern, though rapid fire with the weapon will cause bursts to fly in random directions. At base level, eight bursts can be fired before needing to reload.


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

  • Burst Size is how many shots are fired in a burst.
  • Rate of Fire is the time interval between the last shot in a burst and the first shot in the next burst.
  • Burst Speed is the time interval between shots within a burst.

Therefore the Effective Rate of Fire depends on all of those factors combined, with the Rate of Fire listed in game being only between each burst.

Effective Rate Of Fire
(Per second)
2 RoF 3 Rof 4 RoF 5 RoF 6 RoF
3 Burst Size ~4.54 ERoF ~6.08 ERoF ~7.31 ERoF ~8.33 ERoF ~9.18 ERoF
6 Burst Size 7.5 ERoF ~9.47 ERoF 10.90 ERoF 12 ERoF ~12.85 ERoF

Electro Minelets

Frame Overclock Unstable.png
Icon Upgrade Electricity.png

Electro Minelets is an Unstable Overclock
Each Bullet that touches a surface automatically turns into a Minelet after 0.1 sec, arms for detonation after 0.8 sec, and detonates after 5 seconds. Creatures that go near it will trigger the Minelet and get 6 seconds of Electrocution (3 Electric Damage every 0.25s, and x0.2 Movement speed), each Minelet can only be triggered once. By having the mod "Blowthrough Rounds" it is possible to shoot through Creatures to hit a surface, otherwise the Bullets will not turn into a Minelet.


Each modification that is purchased advances a mastery bar by a single unit.

Mastery unlocks:

  • Three modifications – First Stripe Weapon Paintjob Icon Skin First Stripe.png

  • When the 7 in "BRT7" is interpreted as a second T, it can be read as "BRTT". This is an onomatopoeia of the weapon's firing sound.
