Arrowhead Game Studios has confirmed that Helldivers 2’s explosive GP‑20 Ultimatum grenade pistol takes direct inspiration from the real‑world Stern (or Sten)‑style pistol design. The weapon’s rugged, stripped‑down look and “front‑loaded explosive” concept reflect the same minimalist engineering seen in classic military hardware. Already one of the game’s most powerful sidearms, the Ultimatum now stands as a tribute to the simple yet devastating tools of real‑world warfare.
In Helldivers 2, the GP‑20 Ultimatum is a muzzle‑loaded variant of the GP‑31 grenade pistol. Designed to fit in a sidearm slot, it delivers impact comparable to a small‑scale Orbital Precision Strike. The weapon’s grip guard, short buttstock, and oversized sight recall historical rifle‑grenade launchers while keeping it functional for fast‑paced combat. With a single‑shot explosive round and a small ammunition reserve, it demands precision and smart target selection to make every blast count.

Arrowhead is known for grounding its futuristic arsenal in real‑world military principles, and the Ultimatum perfectly continues that tradition. Developer‑linked insights show that the studio often starts with traditional firearm mechanisms—such as the P‑08 and Webley designs or the simplified Sten‑family layout—then reimagines them within Helldivers’ satirical, over‑the‑top universe. The Ultimatum’s bolted frame, exposed mechanics, and industrial profile echo the Stern‑pistol concept: a cheap, resilient, and brutally effective weapon made for efficiency over elegance.
By embracing the Stern‑style ideology, the GP‑20 Ultimatum finds a balance between improvisation and destructive strength. Its design carries the personality of a weapon built out of necessity—easy to produce, reliable under pressure, and devastating at close range. The distinct “rough‑manufactured” look fits seamlessly within the Helldiver arsenal, reinforcing the satire of mass‑produced military propaganda while remaining a beloved powerhouse on the battlefield.
This real‑world connection adds depth to how players perceive the weapon. Rather than being just another overpowered gadget, the Ultimatum embodies a deeper philosophy—one that values raw function over refinement. For players customizing builds, it serves as a compact grenade launcher that channels the same “make‑it‑work” practicality found in historical firearms, filling the niche of a last‑ditch, do‑everything sidearm.
As Arrowhead continues to explore the military roots behind Helldivers 2’s designs, the Ultimatum’s Stern‑pistol lineage highlights the studio’s artistry in blending authenticity with absurdity. It’s a perfect example of how familiar, grounded weapon design can become something spectacularly chaotic in the hands of Super‑Earth’s finest.
