The GP-20 Ultimatum is one of the most reliable anti-armor solutions in Helldivers 2, and if you’ve been struggling against heavily fortified enemy vehicles or massive walkers, this guide will help you get the most out of it. While not the flashiest weapon in your arsenal, the GP-20 is designed for precision and consistency—two qualities that every squad needs when facing Automatons or bug swarms backed by armored threats.

Why Choose the GP-20 Ultimatum

Compared to other anti-tank options, the GP-20 strikes a balance between firepower and usability. Rocket launchers deliver raw power but often come with heavy reload times, while autocannons require sustained fire to bring down bigger targets. The Ultimatum fits neatly in between: it delivers a decisive hit without being overly clunky, making it a favorite among players who want a dependable tool against armor without sacrificing too much mobility.

Best Situations to Use It

The GP-20 Ultimatum shines in missions where you expect to encounter armored units. Automatons with tanks, walkers, or heavily shielded positions are prime targets. It’s also a strong countermeasure against bug Titans, though careful positioning is key—its reload time leaves little room for error if you miss your shot. Use it when your squad needs consistent anti-armor backup rather than overwhelming fire support.

Effective Loadouts

Pairing the GP-20 with a versatile primary weapon is essential. Many players prefer a reliable assault rifle or shotgun for crowd control while saving the Ultimatum strictly for armor. Support stratagems like supply drops and ammo packs are highly recommended, as you’ll burn through its limited ammo quickly in longer missions.

Team Play Considerations

The Ultimatum works best when coordinated with your squad. One player carrying the GP-20 allows others to focus on crowd clearing and defensive roles. Calling out targets before firing ensures your team doesn’t waste overlapping anti-armor firepower. Remember: every rocket counts, so communication is just as important as aim.

Farming and Progression Tips

If you’re working toward unlocking or upgrading weapons like the GP-20, you may find yourself grinding for resources. Many players choose to buy Helldivers 2 items to speed up progression, especially when aiming to reach late-game content faster. Similarly, some opt to buy Helldivers 2 super credits to ensure they can access the newest gear without excessive farming. Whether you stick to missions or supplement with purchases, the GP-20 will pay off as a must-have weapon against the toughest enemies.

The GP-20 Ultimatum isn’t about flashy explosions or mowing down hordes—it’s about precision, reliability, and keeping your squad alive when an armored threat appears. Mastering its timing, ammo management, and coordination with your team will make you one of the most valuable assets in any operation. If you want a weapon that never lets you down in high-stakes fights, the GP-20 is well worth mastering.
