The GP-31 Ultimatum is one of those weapons in Helldivers 2 that looks intimidating at first but quickly becomes a favorite once you learn its strengths. It’s not the kind of firearm you bring into every mission, but when the situation calls for heavy firepower, few tools clear the field as effectively. This guide will walk you through how to make the most out of the Ultimatum and when it’s worth deploying. What Makes the GP-31 Ultimatum Stand Out The Ultimatum is a shoulder-mounted rocket system that delivers massive burst damage. Unlike rifles or LMGs, its strength lies in sheer explosive output, making it ideal for shredding armored enemies or wiping out clusters of smaller threats. The rockets are slow to reload, but each shot carries enough weight to swing the momentum of a fight. Key characteristics include:
High single-shot damage, especially effective against armored targets.
Moderate area-of-effect splash damage.
Limited ammo supply that requires careful management.
Because of its limited versatility, the Ultimatum works best when paired with a reliable primary weapon. Think of it as a trump card you bring out for boss-tier enemies or when you’re getting overwhelmed. Best Situations to Use the Ultimatum
Armored Bugs and Automatons: Heavy enemies that would otherwise chew through magazines drop much faster when hit with a well-placed rocket.
Defensive Objectives: When holding a position, splash damage helps thin out waves before they close in.
Emergency Crowd Control: One rocket can save your squad if you’re being rushed.
Be careful, though—its blast radius can easily harm allies, so communication is key when playing in squads. Loadout Recommendations Pair the Ultimatum with a fast-handling weapon such as an SMG or assault rifle. This way, you can deal with lighter threats efficiently while keeping the rockets reserved for the right moment. Stratagems that provide additional ammo are also worth considering, given the Ultimatum’s limited supply. Farming and Unlocking Considerations To get your hands on the GP-31 Ultimatum, you’ll need to invest requisition slips. Players who are still progressing might find themselves short on resources, and that’s where farming efficiently comes in. Running missions with high reward multipliers is the most reliable way to build up your stock. Some players even look for helldivers 2 requisition slips for sale as a way to speed things up, though careful grinding usually pays off without needing shortcuts. For those working on their overall gear collection, it’s not uncommon to explore ways to buy helldivers 2 items to round out the arsenal faster. While optional, these methods are sometimes appealing for players who want to focus on late-game builds without as much grind. The GP-31 Ultimatum is not a universal answer to every mission, but it is one of the most satisfying tools in Helldivers 2 when used correctly. Treat it as a situational powerhouse, save it for the biggest threats, and you’ll find it turning the tide in some of your toughest fights.
