Helldivers 2 Gatekeeper: Weaknesses, Anatomy & How to Kill It

The Gatekeeper is one of the nastier things the Illuminate's Appropriators sub-faction can throw at you. A piloted war machine bristling with heavy armor and a rechargeable energy shield, it sits at range and punishes Helldivers who don't know where to shoot. Once you understand its anatomy, though, it stops being scary and starts being a priority target you can dismantle efficiently.

What is the Gatekeeper in Helldivers 2?

The Gatekeeper is an Illuminate Piloted Construct, meaning an actual Overseer pilot sits inside it. It belongs to the Appropriators sub-faction and only appears on planets where the Appropriators are active. You won't encounter one below difficulty 4 (Challenging), so if you're still on lower settings, file this away for later.

Unlike the Veracitor, which shares a similar cockpit design, the Gatekeeper keeps its distance and fights entirely at range. Its two main attacks are:

• A charged twin cannon blast with a large area of effect and enough force to ragdoll Helldivers from a significant distance.
• A rapid-fire tracking attack that telegraphs before firing and slowly locks onto a targeted Helldiver, similar to how a Gazer behaves.

It also has a melee attack, but the wiki notes it rarely uses it and it's easy to sidestep when it does come out.

Gatekeeper anatomy: every part and its health

This is where knowing your target pays off. The Gatekeeper has a 2,500 HP main health pool and a lot of individual parts, most of them sitting behind Heavy armor (AV4). Here's the full breakdown:

The two unarmored weakspots, the CockpitWeakspot and the RearWeakspot, are your priority targets. Both sit at AV1, meaning almost anything penetrates them, and both deal 100% of their damage directly to the main health pool.

How do you deal with the Gatekeeper's shield?

The ShieldGenerator, the horn-like protrusion on the Gatekeeper's forehead, controls the rechargeable energy shield that protects the cockpit. Destroy it and the shield goes down permanently. The catch: the ShieldGenerator itself is Heavy armor (AV4) with only 50 HP. You need a weapon that can penetrate Heavy armor to hit it, but once it goes, the pilot becomes permanently exposed.

The Shield itself has 1,300 HP and Light armor (AV2). It has an overflow cap, so excess damage doesn't bleed through to the main pool. Treat it as a barrier to punch through, not a target worth farming.

Once the cockpit is destroyed, the Pilot inside has 700 HP and Light armor (AV2). Kill the pilot and the entire mech goes down with them.

What weapons work best against the Gatekeeper?

Most of the Gatekeeper's body is Heavy armor, which means light and medium weapons are largely wasted on it unless you're targeting the exposed weakspots. Here's how to think about your loadout:

• Anti-tank weapons (Recoilless Rifle, EAT-17, Quasar Cannon): Needed to crack the Heavy armor on the chassis and cockpit directly, or to destroy the ShieldGenerator in one hit.
• Medium-penetrating weapons: Effective against the Arms (AV3), Hips (AV3), and Legs (AV3). Destroying legs can cripple mobility.
• Light weapons: Useful only against the Shield (AV2), GunWeakspots (AV2), and the exposed Pilot (AV2) once the cockpit is gone. Save your light ammo for the pilot shot.

The most efficient kill path: use a heavy-penetrating weapon to destroy the ShieldGenerator, then either hit the CockpitWeakspot directly or flank to the RearWeakspot. Both are AV1 and feed 100% damage to the main health pool.

Stun effects and the Gatekeeper

Here's a detail most players miss: if you hit a Gatekeeper with a stun effect, such as a G-23 Stun grenade or an A/M-23 EMS Mortar Sentry, the Overseer pilot inside can be seen physically smacking at the controls trying to restart the mech. It's a neat bit of animation, and more practically, it gives your squad a window to reposition or land shots on the weakspots without the Gatekeeper returning fire.

Stun effects don't permanently disable the Gatekeeper, but the window they create is long enough to be genuinely useful on higher difficulties where the charged cannon blast is a squad-wipe risk.

How does the Gatekeeper compare to similar Illuminate units?

The Gatekeeper sits above the Veracitor in the Appropriators roster. Both are piloted mechs with cockpit-based kill conditions, but the Gatekeeper is heavier in every meaningful way: Heavy armor across most of its body versus the Veracitor's lighter profile, a rechargeable energy shield the Veracitor lacks, and a preference for staying at long range rather than closing distance.

The Harvester comparison is also worth noting: the Gatekeeper's ShieldGenerator functions identically to the Harvester's, sitting on the head and controlling a shield that protects the core. Players who've already figured out the Harvester will recognize the pattern immediately.

Quick reference: Gatekeeper priority targets

• First priority: ShieldGenerator (forehead horn) with Heavy-penetrating weapon. 50 HP, permanently disables the shield.
• Second priority: CockpitWeakspot or RearWeakspot. Both are AV1 with 100% damage transfer to Main.
• Third priority: Pilot (700 HP, AV2) once the cockpit is destroyed.
• Avoid: Shooting the Shield directly. It has an overflow cap and won't bleed damage through.

The Gatekeeper added to Helldivers 2 in patch 1.006.100 (March 17, 2026) as part of the Appropriators sub-faction, so some community testing is still ongoing. The anatomy data above reflects current wiki figures, but specific weapon damage values against each part are still being documented.
