Escort Duty is a mission type in Deep Rock Galactic.

Escort the Drilldozer while it makes its way to the Ommoran Heartstone.

Protect the Drilldozer[]

Escort Duty involves escorting a Drilldozer (also known as the Dozer, and affectionately named "Doretta" by the Dwarves), a large automated drilling machine, protecting it from attacking Creatures and repairing damage done to it. The Drilldozer's health is segmented into three parts: the left side, right side, and body. The left side will take damage until it breaks, then the right side, then the body. Damage dealt to any part of the Drilldozer will only affect the active segment. However, it can only be repaired from the area of the Drilldozer it maps to. When a segment reaches 0%, Mission Control will announce that the Drilldozer has taken permanent damage. The damaged segment cannot be repaired anymore and the next segment will begin taking damage. If the Drilldozer's body runs out of health, the mission fails.

The Drilldozer's speed is determined by how many Creatures and Dwarves are nearby. The more Creatures are present, the slower it will move, leaving it vulnerable to attack.

When the Drilldozer runs out of fuel, it must be refueled by extracting oil from Oil Shale. This is done using the Fuel Canisters taken from back of the Drilldozer. The beams emitted from the Canisters liquefy the shale, which automatically collects the fuel. Oil Shale can be mined normally (though it requires four pickaxe hits to break), but Dwarves cannot pick up the chunks. A delay similar to laser mining the ore is also applied when chunks are collected with the Canisters. It is faster to use the Canisters on the Oil Shale directly. Once a Canister is filled, it must be inserted back into the Drilldozer. When it is fully refueled, the Drilldozer must be manually restarted.

The Drilldozer will eventually arrive at the Ommoran Heartstone, a large spherical structure. The Drilldozer must be manually started again to begin drilling into the Heartstone. Swarms will spawn frequently throughout this entire process. The Ommoran Shell's lifebar is divided in 4 parts, the first two phases last about 60s, the second phase last about 75s, the last phase last about 100s, for a total of ~300 seconds (5 minutes) with the interval between the different phases. Each time a phase ends, the heartstone releases an explosion which will heavily damage the players the closer they are to the drilled part of the core.

The first phase will have a guaranteed swarm spawn.

During the 2nd phase, once the outermost shell is broken, the Heartstone will summon Flying Rocks, dropping them onto the Drilldozer. These deal 50 Kinetic damage on a 2.5m radius, with the damage scaling with Hazard level.

The third phase will have another guaranteed swarm spawn.

For the 4th phase, when the last shell is exposed, Ommoran Beamers will raise out of the ground, emitting lasers at the Drilldozer, dealing damage to it. On top of that, enemy spawn rate is increased (but not as much as in a swarm). These crystals must be mined or drilled out to stop the beams. The drilling is completed when the Heartstone itself is exposed, which explodes for the last time and heavily damages only enemies and not the players. It can then be picked up and deposited. Doing so completes the primary objective. Doretta's head can also be taken back in the Drop Pod. This yields no monetary or experience benefits, but the head will appear in the mission complete screen, off to the side.

Compared to the caves seen in other mission types, most of the "rooms" are not connected by tunnels or Compressed Dirt barriers. The only way to proceed is by accompanying the Drilldozer, which is programmed to follow a path to the Ommoran Hearthstone. This encourages the team to stay by the Dozer and protect it. Wherever the Dozer digs creates large tunnels in its wake, which can be navigated through later and are often necessary to use for the Extraction phase. The Dozer will only ever run out of fuel in the middle of a room, making Oil Shales easier to locate and collect. The Heartstone itself is found in a larger room and is fairly easy to spot given its dark red glow.


Primary Objective[]

  • Refuel the Drilldozer 1-2 times
    • Continue escort

The amount of times the Drilldozer will need to be refueled depends on the mission length.

Fleas Exterminate 10 Fester Flea

Gunk Seed Collect 12 Gunk Seed

Hollomite Collect 25 Hollomite



  • This mission type was added in Update 32: Roughnecks At Work.
  • Repairing the Drilldozer uses various tools instead of the typical hammer used when constructing/repairing objects, including a pipe wrench and an oil can.
  • It is possible to pet the Drilldozer by pressing the [USE] ("E" by default) key on its "head", found at the top of its body behind the drill.
  • Pressing the Salute key while holding a Fuel Canister causes the dwarf to say a beer-holding salute line.
