Escort Duty is a mission type in Deep Rock Galactic.

Escort the Drilldozer while it makes its way to the Ommoran Heartstone. Escort Duty is the fifth unlockable mission type, following Point Extraction.

Protect the Drilldozer[]

This mission 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 Dozer's health is segmented into three parts: the left side, right side, and body. The left side will take the damage first until it breaks, then the right side second, then the body. Damage dealt to the Dozer from any location will only affect the active segment. However, it can only be repaired from the area of the Dozer it corresponds to. When a segment reaches 0%, Mission Control will announce that the Dozer has taken permanent damage. The damaged segment cannot be repaired anymore and then the next segment will begin taking damage. If the Dozer runs out of health completely, the mission fails. Multiple players increase the speed at which the damaged segments get repaired at a rate of 10–15% HP per second per dwarf.

The Dozer'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 Dozer runs out of fuel, it must be refueled by extracting oil from Oil Shale with the Fuel Canisters taken from back of the Dozer. 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 rather than mining it with a pickaxe. Once a Canister is filled, it must be inserted back into the Dozer. When it is fully refueled, the Dozer must be manually restarted.

The Dozer will eventually arrive at the Ommoran Heartstone, a large spherical structure. The Dozer 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 60 seconds each, the second phase lasts about 75 seconds, and the last phase lasts about 100 seconds, for a total of roughly 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 and knockback dwarves in a 35m radius.

Phase One: Swarm trigger.
Phase Two: Summons Flying Balls to slam into Doretta - these deal extreme damage but can be destroyed before they hit the Dozer.
Phase Three:
  • Intensified swarm trigger with increased enemy presence.
  • Starts spawning Ommoran Beamers: large, destructible crystal towers which fire laser beams at the Dozer, dealing constant damage.
Phase Four: The Heartstone emits a pulsating energy wave at 3 second intervals as the Dozer nears the core. This wave creates a slowing effect that hampers the movement of both Dwarves and enemies caught within its radius. The slowing effect stacks with each pulse wave and lingers for 5 seconds after the wave passes.

At the conclusion of Phase 4, The Heartstone will emit a final shockwave that instantly kills all nearby enemies in a 35m radius. The Heartstone can then be extracted and strapped onto the back of the M.U.L.E., where the Drop Pod extraction process can begin. The Dozer's head pops off and is considered retired. A dwarf can grab the Dozer's head and carry it back to the Drop Pod, where it will automatically move to floor of the Drop Pod, appear during the mission end screen, and in the Space Rig only once.


See: Flying Balls for more information.


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 Dozer, which is programmed to follow a path to the Ommoran Hearthstone, encouraging the team to stay by the Dozer and protect it. Wherever the Dozer digs, it creates large tunnels in its wake, which can be navigated through later and are often necessary for the Extraction phase. The Dozer will only ever run out of fuel in the middle of a room, making Oil Shale easier to locate and collect. The Heartstone itself is found in a larger room and is fairly easy to spot, given its dark red-purple glow.


Primary Objective[]

  • Unpack Heavy Cargo Drop
  • Start the Dozer
  • Escort the Dozer
  • Refuel the Dozer 1-3 times
    • Continue escort
  • Crack the Shell of the Ommoran Heartstone
  • Return the Ommoran Heartstone

The amount of times the Dozer will need to be refueled depends on the mission length. The amount of Oil Shale required to refuel the Dozer depends on the mission complexity.

Length Complexity Refueling Stops
Cave length 2 Cave complexity 1 1
Cave length 2 Cave complexity 2 1
Cave length 2 Cave complexity 3 1
Cave length 3 Cave complexity 2 2
Cave length 3 Cave complexity 3 2
Cave length 3 Cave complexity 3 3

  • This mission type was added in Update 32: Roughnecks At Work.
  • Repairing the Dozer 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 Dozer by pressing the [USE] 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.
