The Illuminate faction in Helldivers 2 brings a completely different kind of battlefield pressure compared to what Helldivers face against Terminids or Automatons. Their units rely on shields, swarm tactics, and high-tech constructs, forcing players to rethink their usual loadouts.

From waves of Voteless drones to heavily protected Overseers, massive Harvesters, and the recently introduced Appropriators sub-faction — featuring units like the Veracitor and Gatekeeper constructs—the Illuminate demand weapons that can handle both durability and crowd control at the same time. Because of this unique combat style, the primary weapons that dominate the current meta against the Illuminate are often very different from those preferred on other fronts.

With that in mind, here are the five most commonly selected primary weapons used by Helldivers when engaging the Illuminate as of April 2026.

1. SG-97 Sweeper (13.6%)

The Sweeper shotgun is only obtainable through the Superstore for 400 Super Credits and appears during the Entrenched Division rotation. While it ranks as the second most popular choice against bug enemies, it actually becomes the number one primary weapon when facing the squids.

The constant pressure from Voteless swarms makes it especially effective, as its full-auto flechette fire can shred them faster than nearly any other primary option. On top of that, its medium armor penetration and strong DPS allow it to remain effective against tougher targets like Overseers and Fleshmobs. And when enemies close the distance, the integrated bayonet proves it’s far from just a visual detail — it becomes a very real answer to charging Voteless at close range.

2. 2. SMG/FLAM-34 Stoker (11.5%)

The Stoker SMG is the flagship weapon of the Entrenched Division warbond, which launched in March 2026 and costs 1,000 Super Credits. Its rise from fourth place on the Terminid ranking to second place in this matchup is largely due to how effectively its dual-mode functionality adapts to the diverse Illuminate combat patterns.

Illuminate encounters constantly alternate between long-range pressure from Overseers and sudden close-range rushes from Voteless swarms. The Stoker is built to handle both scenarios seamlessly without requiring a weapon swap — its SMG configuration excels against Overseers and Watchers, while its incinerator mode is perfect for burning down Voteless before they can close the gap.

3. AR-2 Coyote (11%)

The Coyote rifle comes from the Dust Devils premium warbond, priced at 1,000 Super Credits and unlocked at 35 medals. It already holds the highest pick rate among Terminid loadouts, and it transitions into Illuminate missions with almost no drop in effectiveness.

Its medium armor penetration allows it to cut through Overseer and Elevated Overseer defenses with ease, while its incendiary rounds are extremely efficient at clearing Voteless — often taking them down in one or two hits and allowing burn damage to finish the job, which helps conserve ammunition. Beyond swarm control, the Coyote also performs reliably against heavier targets like Harvesters when aimed at weak points such as their joints, outperforming most standard assault rifles in that role.

4. R-36 Eruptor (7.8%)

The Eruptor appears on the second page of the Democratic Detonation premium warbond, costing 1,000 Super Credits and unlocking at 60 medals. After receiving its heavy armor penetration buff, it has gradually established itself as a reliable cross-faction weapon in Helldivers 2, and the Illuminate battlefield is no exception.

Its explosive ammunition is highly effective at clearing clustered Voteless groups, but the weapon’s true strength lies in its range advantage. While Harvesters are usually dealt with using support weapons, the Eruptor offers one of the few primary-slot solutions capable of contributing meaningful damage to them, thanks to its heavy armor penetration. This allows players to steadily chip away at large targets while still engaging Overseers and Fleshmobs safely from a distance.

5. AR-23P Liberator Penetrator (6.4%)

The Eruptor appears on the second page of the Democratic Detonation premium warbond, costing 1,000 Super Credits and unlocking at 60 medals. After receiving its heavy armor penetration buff, it has gradually established itself as a reliable cross-faction weapon in Helldivers 2, and the Illuminate battlefield is no exception.
