Deep Rock Galactic – Gunner Build Guide & Class Tips

Need a gunner build guide and tips for the versatile and strong damage dealing class in Deep Rock Galactic? The gunner is a popular class in the dwarf mining adventure and has a number of flexible build options that are explored below to give you multiple potential choices in designing your ideal gunner.

While the best gunner build will always have an element of personal preference and playstyle there are some clear winners in the respective equipment choices which combined with best perks and Bosco setup will ensure you are ready to tackle the highest hazard game levels. This gunner guide is targeted at the new to intermediate player of both the character and Deep Rock Galactic in general and covers the gunners role, basic gunner tips and how to create the best gunner build for you.

Gunner Overview

As the name of this dwarven class suggests the gunner specialises in gunning down enemies with high damage per second that allows him to protect others on his team. This is also reflected in the equipment options granted to the gunner with miniguns, hard hitting revolvers, a deployable shield and powerful area of effect grenades. As with all dwarves you have a utility movement piece of equipment and for the gunner this is the handy zipline that provides a wealth of team support to other classes.

While the gunner is a capable solo class his equipment shines in the multiplayer environment as a blended damage support class. Players that master both these playstyles will be the ones that can repeatedly promote the rank of their gunner time and time again.

Gunner Specific Tips

Using the gunner in high hazard levels and turning you from a beginner to master gunner player with the following tips can ensure you are getting the most out of your gunner kit. With these tips in mind you can survive more, finish missions faster and add significantly more value to your team in multiplayer.

  • Chokepoints and flat ground are vitally important to the gunners damage output. Fighting near beneficial locations like this that allow you to hold down the trigger on your primary weapon will save you ammo and improve your damage output. This also includes positioning yourself so all enemies are coming from one direction where possible to prevent wasted ammo in changing directions or having to reset your primary weapon.
  • While the shield is one of the gunner’s best assets you’ll want to be careful when activating it due to the limited duration it has per cast. Prioritise point defence locations that your team needs to defend for an extended period or using it on a downed ally (or multiple) to secure a revive.
  • Ziplines are one of the most flexible movement tools in Deep Rock Galactic and specialise in passing wide caverns or providing a reusable method to scale up and down a complex cave.
  • Given the speed up required for your primary weapons to reach maximum accuracy your focus should always be on large groups of enemies or durable tough enemies. Leaving the weaker enemies to your allies or secondary weapon can stop you from slowing down your movement.
  • With the wealth of area of effect damage coming from the gunner the friendly perk that reduces friendly fire damage by 50% can be a valuable selection.
  • Given the gunner is generally a slower character than others when moving around a cave of high complexity your focus should be on the ground level minerals and particularly Nitra given the ammo hungry nature of your damage output.
  • Firing your weapons while using a zipline can be an effective method to stay out of harms way and give you great oversight of a battlefield area.


Best Gunner Builds Guide

With the basics of the gunner’s role in a Deep Rock Galactic mining team and specific gunner tips out the way it’s time to dive into the best gunner builds available. As with other mechanics of Deep Rock Galactic there is an element of personal preference and mission type that needs to be considered when building your ultimate gunner.

With this in mind the guide below is designed to point you towards the strongest options and arm you with the necessary information to mix and match them into a build that feels right for you.

Gunner Primary Weapons

The Gunner primary weapons are both hard hitting with a mini gun and explosive shell auto cannon that are equally deadly from a damage perspective. Either are perfectly viable to take into any hazard level with both having specific mechanics that will change how you use them in combat.

deep-rock-galactic-gunner-minigun-build“Lead Storm” Powered Minigun: Has a small wind up time before maximum firing speed and accuracy are reached that makes it not the ideal option for small groups of enemies. The minigun does not need to be reloaded but does have an overheat mechanic that prevents you from firing endlessly. The best minigun build modifications focus on giving you additional ammo, damage boosts and a reliable method to manage the overheat.

  • Tier 1 – Improved Motor
  • Tier 2 – Oversized Drum or High Velocity Rounds
  • Tier 3 – Blowthrough Rounds
  • Tier 4 – Variable Chamber Pressure
  • Tier 5 – Cold As The Grave
  • Overclock – Lead Storm or A Little More Oomph!


“Thunderhead” Heavy Autocannon: Available from level 10 onwards this gunner primary weapon alternative does require reloading and uses an explosive round that explodes after hitting terrain or an enemy. Accordingly it provides significantly more area of effect (aoe) damage than the minigun although still has a fire rate wind up and the aoe is not large enough to forego good aim completely. Many of the modification options either push the weapon towards a direct damage dealing piece of equipment of buff aoe so players should choose one to focus on.

  • Tier 1 – Increased Calibre Rounds or Expanded Ammo Bags
  • Tier 2 – Improved Gas System
  • Tier 3 – High Velocity Rounds or Loaded Rounds
  • Tier 4 – Shrapnel Rounds
  • Tier 5 – Feedback Loop
  • Overclock – Composite Drums or Splintering Shells or Carpet Bomber

Gunner Secondary Weapons

Gunner secondary weapons are designed to deal with small groups of enemies given the fire rate wind up times on the primary weapon choices. They are also viable options for when you are moving through the map given the heavy nature of their larger weapons.


“Bulldog” Heavy Revolver: Usually the preferred sidearm of most gunners in the Deep Rock Galactic community due to the hard hitting damage and stun chance although this comes at the cost of a low magazine size. Modifications focus on maximising the already high damage output and making this weapon ideal for weak point shots on the move that your primary weapons simply aren’t designed for.

  • Tier 1 – Quickfire Injector
  • Tier 2 – Increased Calibre Rounds
  • Tier 3 – Hollow-Point Bullets
  • Tier 4 – High Velocity Rounds
  • Tier 5 – Dead-Eye
  • Overclock – Elephant Rounds


BRT7 Burst Fire Gun: A unique weapon that fires a burst of 3 when the trigger is pulled that can make it difficult to use on moving enemies without practice. The larger magazine size does make it useful for dealing with medium sized mobs but usually the gunner will be using a primary weapon for these occasions. Modifications for this gun focus on boosting up damage and adding stun utility.

  • Tier 1 – High Velocity Rounds
  • Tier 2 – Recoil Dampener
  • Tier 3 – Increased Calibre Rounds
  • Tier 4 – Hollow-Point Bullets
  • Tier 5 – Burst Stun
  • Overclock – Composite Casing

Gunner Equipment

As mentioned already the gunner equipment provides a zipline launcher for your teammates and your own dwarf to use along with a shield generator to protect key locations. Both of these provide significant support utility on top of your damage focused weapons and make a gunner an invaluable addition to a full team.

Zipline Launcher: Ideal for moving across wide gaps and vertical movement the zipline is a useful team orientated tool. Upgrades are focused on improving usability and protecting yourself or teammates from any mishaps when using the zipline.

  • Tier 1 – Upgraded Connection Joint
  • Tier 2 – Reinforced Cable
  • Tier 3 – Disconnection Protection


Shield Generator: The ultimate defensive ability in Deep Rock Galactic to keep you and your allies safe in a single location. Modifications are designed to ensure you get more shield generator time through duration and recharge.

  • Tier 1 – Streamlined Integrity Check
  • Tier 2 – Large Capacitors
  • Tier 3 – Improved Efficiency


“Barracuda” Armour Rig: Like all dwarves the gunner has an upgradable armour rig to improve their survivability. Given the gunner is often diving into the thick of fights we opt for quicker shield regeneration, extra health pool and area of effect stun to help you gain some distance from your attackers if your shield does break.

  • Tier 1 – Improved Generator
  • Tier 2 – Healthy
  • Tier 3 – Reactive Armour
  • Tier 4 – Static Discharge


Gunner Throwables

All three of the gunner throwables are powerful damage dealers that complement his already high damage output potential. While each has their own strong points they have some differences to consider in choosing the right variation to complete your personal gunner build.

Sticky Grenade: Useful in setting up a defensive location with the sticky mechanic this option also comes with a fear and lets players can carry up to 6 compared to 4 of your other options. It’s a reliable default option that you start with and for the lower hazard levels is perfectly suited to dispatching swarms.

Incendiary Grenade: A good option for narrow passageways as you can lay fire down for any enemies that charge through. As most of the damage is linked to this fire element though it’s not ideal for open spaces.

Cluster Grenade: The best grenade for your gunner builds the cluster grenade adds a nice amount of area of effect coverage but does require some practice to master.
