Deep Rock Galactic Wiki

R&D came up with a brilliant idea for helping out our Pest Control teams: Project Omen - a vast network of interlinked Modular Extermination Towers, strategically inserted into caves all over Hoxxes. However, much to their regret, the Exterminators turned out to be just as dangerous to our own people as the bugs they were supposed to protect us against! So, the strategy is clear: Project Omen needs to be shut down. However… for security reasons, that can only be done through a… hands-on approach, by our esteemed ground teams.
Get in there, find and activate the Exterminator, engage the Maintenance Pads to expose the machine Cooling Tanks, and blow them to bits. Easy. Well, and you have to do so within a limited time window or the device goes into Lockdown.

PS: Do note, the Exterminators can be constructed from a variety of different modules, so for your personal safety, do take care to learn the patterns of each. R&D aren’t in the business of making kids’ toys, after all...
— Official Description

The Omen Modular Extermination Tower is a powerful stationary defense emplacement initially sent by Deep Rock Galactic during the initial landing and exploration of Hoxxes during Project Omen. The original purpose of these towers were to clear out any hostile infestations in mineral-rich deposits within a complex network of these modules. This is to make mining far safer for the Dwarves once they land on the planet. However, like the BET-C, things did not go as planned. The towers had a software glitch and it quickly turned out that they are just as likely to fire on the Dwarves as much as the Glyphids. It is now in the task for Deep Rock Galactic to destroy any Tower they encounter.

The Tower itself is the only Machine Event-exclusive boss enemy encountered under the Omen Modular Exterminator category. Players only have a few minutes to take down the tower before it enters into lockdown. Destroying the tower rewards players with a Core Infuser upgrade.


The Extermination Tower is a tricky enemy to fight due to the combination of the 3-minute time limit and its wide-range damage arcs of its modules. Moreover, its only weakspot are its green-colored cooling tanks which periodically open up on one of its three modules, outside of this brief moment of weakness, the Tower is effectively invulnerable to all types of damage. To expose these tanks, players will be required to stand on top of three different maintenance platforms around the tower until authorization is granted. Each platform will expose a different tower, which will be indicated in a pop-up display. Care must be taken as each module has its own health bar, so they must all be destroyed to complete the Machine Event.

The platforms are always linked to the same layer of the tower. When standing on the Core Infuser:

  • The left and right maintenance platforms will randomly open the middle or top module.
  • The opposite maintenance platform is always linked to the bottom layer of the tower.

The cooling tanks are weakpoints with a multiplier of ×1 (so weapons with weakpoint damage do more damage to them).
The Omen Modular Exterminator also has a 70 % resistance to explosion, fire and frost damage.

  • The Drone Replicator (3 cooling tanks) will periodically deploy slow-moving drones that will home in on a player. These drones will explode and deal high damage upon coming in contact with any solid object or creature. They can be difficult to spot, but can be easily destroyed with ranged weapons. The tower will have at least one active drone out at all times, and spawn a new one if none are active. Drones will launch every 6 seconds, regardless of if the previously launched drone has exploded or not. If a drone does not explode 10 seconds after selecting its target, it will fly off in the direction it is facing.
  • The Heavy Burster (3 cooling tanks) will slowly rotate around the tower, emitting a red targeting light. If the light passes over a player, a machine gun will begin firing on them, dealing severe damage. Moving out of the light will stop the machine gun from firing.
  • The Twin Slicer (2 cooling tanks) lasers will periodically perform sweeps around the tower at varying heights. These lasers can be avoided rather easily, as they may not be pointing towards the ground most of the time.
  • The Radial Pulse-Gun (3 cooling tanks) is always at the bottom layer of the tower. Once per second, the tower will rotate and then fire. It will send out slow-moving purple beams at waist-level, which will deal extreme damage when touched. The beams can be avoided by dodging, jumping over them, or hiding behind a solid object. An Engineer can also place platforms on top of the maintenance platforms to elevate the players above the beams. Due to the large area it covers and the amount of damage each beam causes, this module must be taken out in priority in order to ease the exposition of the other modules' cooling tanks.

This event is often claimed to be the hardest of the 4 Machine events to the extent that some dwarf teams decide to ignore it so they won't lose the progress already achieved due to the large amount of dangerous attacks deployed by each module. Prediction and awareness is the key to succeed. Each dwarf will perform more or less against this particular event:

  • The Driller will struggle the most when it comes to dealing damages to the cooling tanks, since the Omen Modular Exterminator has a 70% resistance to explosion, fire and frost damage, all three akin to the Driller's CRSPR Flamethrower, Cryo Cannon and Satchel Charge, the later however is still powerful enough to deal a considerate amount of damage to the Radial Pulse-Gun. On the other hand, his Reinforced Power Drills can allow him to dig trenches, giving cover to the team.
  • The Engineer is relatively efficient, with good damage overall and the potential to use elevated platforms to help the team avoid the Radial Pulse-Gun's beams while holding their position on the maintenance platforms. Molly can also be used to measure Engineer's platforms, as placing them right above her (with the bottom of platforms not clipping into her), and connected to a wall, will allow them to remain in the air relatively damage free from the pulse-gun and still allow the dwarf on top to safely access the maintenance platform. His turrets are also efficient against flying drones and to add additional fire power against the cooling tanks.
  • The Gunner, with the help of his Shield Generator, can allow him to hold position on one of the maintenance platforms with little trouble and revive downed teammates safely. His high damage weapons, be they primary or secondary, can also dispatch the cooling tanks quickly.
  • The Scout, thanks to the accuracy of his primary weapons, can take out the cooling tanks just as efficiently as the Gunner can. His lack of defensive capabilities however, forces him to rely on hit and run tactics.
  • The M.U.L.E can be parked on top of the maintenance platforms and be stood upon to avoid the waves from the pulse-gun, the dwarf standing on Molly can still access the maintenance platform.

 • The objective is to destroy all the cooling tanks on the Modular Extermination Towers in the allotted time.

Health and Armor[]

The health of each cooling tank is the same, the module’s health will depend on the number of cooling tanks it has (2 or 3), each cooling box having a base health of 600.

Homing Drone[]

The Homing Drone is a suicide UCAV akin to a flying bomb. These drones only spawn if the Extermination Tower has a Drone Replicator module. The module can spawn an infinite amount of UCAVs until it is either destroyed of the timer runs out and the Tower enters lockdown. The Drone is propelled by three jets and carries three large sticks of explosives.

Once a Drone spots a player, it will immediately fly towards them and detonate, dealing as much damage as a Glyphid Exploder. However, like Exploders, these Drones are as weak as one, so it does not take much to take them down. It is advised to take cover whenever a Drone is spawned as they are unusually quiet; making surprise attacks common.

  • The Extermination Tower is considered by many, to be the most difficult and annoying Machine Event to complete. This is due to the fact that the Tower's extremely wide 360 degree radius and high damage makes dodging its attacks incredibly difficult. Combine this with a time limit and a very small weak spot that only opens up by standing in the open, means that dealing with this thing is no easy matter.
  • For Drillers which are often as the most disadvantaged when it comes to dealing with this Tower, an alternative strategy is to dig a small burrow right next to the Tower before activating it. The burrow provides the Driller some much needed cover and allows the player to stay within range of their short-ranged weapons to be effective.
  • Engineers can build platforms above the Omen's platforms that will complete the scan while avoiding the laser attacks. Ensure you place them high enough to avoid the laser as they can destroy your platforms.
  • Supply pods are indestructible and can be placed on platforms to avoid the lasers and complete the scans. However, the battery-exposing platforms don't allow for resupplies to be called upon them, so an engineer is needed to place a platform above the Omen access platforms if this strategy is to be utilized.
  • The Homing Drone is a direct reference and political commentary towards former U.S. President Barrack Obama who lead a massive drone strike campaign in Yemen.
