The Machine Gun and Gatling Sentries are two stratagems that form the backbone of every defensive position inHelldivers 2. They are both automated turrets capable of targeting (shredding) enemies inside a large 360-degree radius.
The Machine Gun Sentry and Gatling Sentry are quite similar except for a few differences that the in-game descriptions do not detail enough. Since both sentries can be unlocked early on inHelldivers 2, you might want to save yourhard-earned Requisition Slipsby unlocking only one of them. So which one should it be? Let’s find out.

you may summon (use) both the Machine Gun and Gatling Sentries at the same time. That, however, would be akin to wasting a stratagem slot that can go to any of theother sentries inHelldivers 2.
Should You Get the Machine Gun Sentry or Gatling Sentry in Helldivers 2?
TheGatling SentrySentry does more damage per second inHelldivers 2than the Machine Gun Sentry because of its superior fire rate. While both do the same damage per bullet, the Gatling Sentry’s insane fire rate allows it to cut down groups of enemies much faster.
You will realize why the Gatling Sentry is the better choice inHelldivers 2whenplaying higher-difficulty missions. Enemies spawn much faster and in greater numbers in level 7 or higher missions. You will be facing many small (trash) enemies and enemies with large health pools. The Gatling Sentry will shred all of them, allowing you to focus onarmored enemies such as Chargers inHelldivers 2. The Machine Gun Sentry, though, will not be as effective.

That fire rate, however, also means the Gatling Sentry will run out of ammunition much quicker. It keeps firing while switching between targets, wasting precious ammunition. The Machine Gun Sentry, on the other hand, lasts longer on the battlefield to provide continuous support because of its slower fire rate and how it only fires after locking on to a target.

Light Armor
If you are anew player with a solo build inHelldivers 2, get the Machine Gun Sentry for lower to mid-difficulty missions. If you are looking for a long-term investment, get the Gatling Sentry for suicide to helldive missions.
Machine Gun Sentries thrive in lower difficulties because the missions only have squishy enemies. Use them to defend objectives or clear outposts for longer periods. Gatling Sentries will waste half of their ammo while switching between targets in the same situation.

The Robotics Workshop has excellentship modules to upgrade sentries inHelldivers 2. you’re able to increase their ammo count by 50 percent and make them rotate faster to target more enemies. In other words, you get to remove all the weak points from the Gatling Sentry and make it even better in the game.
If your Gatling Sentry locks on to a heavily armored enemy like Annihilator Tanks, step in quickly to destroy them yourself. If not, the Gatling Sentry will waste all of its ammo and go on cooldown.
