The corrosive sludge pump is what happens when the maintenance staff are left with too much time on their hands. A complicated network of piping, distillation bottles, and safety valves results in a very capable device indeed - lobbing globs of toxic waste at those you disapprove of has never been so fun!

— Item Description

The Corrosive Sludge Pump is an unlockable primary weapon for the Driller. It is a large sludge dispenser that fires corrosive sludge, capable of melting enemies. It consists of a number of pipes and valves wrapped around a fuel tank with a nozzle.

The Sludge Pump has two firing modes; Tapping the fire button will fire a single fragment of sludge whereas holding the fire button and releasing will fire a sludge bomb that causes several fragments to fly out upon impact.

When a corrosive projectile impacts an enemy, that enemy becomes visibly coated with sludge and takes damage over time (DoT). When the projectile impacts a surface, it creates a corrosive puddle that causes DoT to any enemy walking over it, along with slowing them down.

Modifications[]

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

Neg.svg Charged projectile does not break into fragments on impact
The addition of finely tuned timed separation compounds cause the charged shots to leave a trail of sludge as they fly through the air. However the projectile depletes its mass as it flies, dealing less impact damage as fragments separate and completely expiring once all fragments are dropped.

  • Damage is how much damage is dealt upon direct impact of an uncharged shot.
  • Charged Area Damage is how much damage is dealt within the damage radius around the impact of a charged shot.
  • Charged Fragment Damage is how much damage is dealt by each fragment spawned by a charged shot.
  • Charged Fragment Count is the amount of fragments spawned by a charged shot.

Corrosion Mechanics[]

  • Effects Duration is the amount of time in seconds that corrosion affects an enemy when it is directly impacted by a corrosive projectile.
    • Enemies walking through a corrosive puddle does not apply/refresh this effect.
      • Damage (per tick): 5

Unique Modifications[]

Unique Overclocks[]

Goo Bomber Special[]

Frame Overclock Unstable.png
Icon Upgrade Special.png

Charged Shots now drop their Fragments straight down while flying, instead of upon impact. Every Fragment dropped reduces the damage of the main projectile. After every Fragment has been dropped, the main projectile is destroyed.

Sludge Blast[]

Frame Overclock Unstable.png
Icon Upgrade Shotgun Blast.png

Changes the Charged Shot into a shotgun-like blast of the Fragments instead of a larger projectile. Fragments use the Charged Shot's damage instead. Charge Shots are also launched at a 3° angle instead of the normal 9° angle.

Mastery[]

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

Mastery unlocks:

  • Three modifications – First Stripe Weapon Paintjob Icon Skin First Stripe.png
  • Seven modifications – Deepcore Weapon Paintjob Icon Skin Deepcore.png
  • All modifications – The Company Special Weapon Paintjob Icon Skin The Company Special.png

Trivia[]

  • The Corrosive Sludge Pump's weapon prototype used the Platform Gun model and its goo blobs more closely resembled the goo generated by Goo Sacks.
