Game Guide by Ragib Rawnak on Apr 02, 2026

The A.T.A.G Distribution quest tasks you with safeguarding a Reactor, using a tank designed for the job. The mission isn't straightforward, though.

The Reactor is fragile, and your weaponry could easily do more damage than good. To succeed, you must avoid aiming your weapons directly at the structure.

Instead of firing at every enemy you see, stay at the top and wait for the targets to move into range. Shooting at a distance is often a waste of your energy and does not hit the targets effectively in Crimson Desert.

Managing the Initial Waves

When the first groups of Insects appear, resist the urge to use Suppressive Fire. This ability is not very helpful for this specific challenge.

You should let the enemies get very close to your position before you start using your Machine Gun.

By waiting until they are nearby, you can destroy many more of them at once without draining your stamina. Keep your focus on the clusters that get closest to the Reactor to keep its health bar high as you move into the later stages.

Prioritizing Targets and Stamina

The third wave brings larger enemies and flying units that require more focus. Focus on the small flying insects initially; they inflict damage the moment they appear. Other foes, such as those with balloons, must be in close proximity to their target before detonating.

Your rockets are ideal for dealing with these balloon-carrying enemies, particularly when they're clustered. An explosion from one can often take out others nearby in Crimson Desert.

Clearing the Final Swarm

As you reach the end of the quest, a large swarm will approach from the right side. Do not fire your Rockets or guns while they are far away, as the shots rarely hit more than one enemy in a pack.

Continue to conserve your stamina and wait for the group to close the gap. Even if some enemies get through and deal a little damage, you only need to finish with some health remaining to win.

Once you pop the last Balloon enemy, the mission will end and the Reactor will be safe in Crimson Desert.
