In Helldivers 2, mastering your weapon loadout isn't just about picking the biggest gun with the loudest boom—it's about understanding the perks that turn ordinary weapons into mission-winning tools. Whether you're holding the line during a Terminid swarm or surgically striking Automatons, the right weapon perks can dramatically shift your effectiveness on the battlefield.

Here are 12 weapon perks in Helldivers 2 that are absolutely worth trying out—and possibly building your entire loadout around.

1. Armor-Piercing Rounds

Perfect for cutting through enemy armor, these rounds are a must-have when dealing with Automatons. Pair this perk with precision weapons like the DMR or the Anti-Materiel Rifle for maximum impact.

2. Explosive Payload

Grenade launchers and certain shotguns benefit heavily from this perk. It deals area damage on contact, making it a solid choice for crowd control. If you're looking to buy Helldivers 2 medals to unlock weapons faster, consider grabbing a launcher that supports this perk early on.

3. High Capacity Magazines

For players who prefer LMGs or SMGs, this perk is all about staying in the fight longer without reloading. It's ideal during defensive missions or when your squad needs consistent suppression fire.

4. Thermal Sights

Night missions and foggy biomes can limit visibility. With Thermal Sights, enemies light up like beacons, helping you spot ambushes before they happen. It's particularly effective in synergizing with stealth or sniper builds.

5. Overpenetration

A dream perk for sharpshooters, Overpenetration lets bullets pass through enemies and hit targets behind them. It's especially valuable during Terminid tunnel encounters where enemies bunch up.

6. Fast Reload

Under constant pressure, reloading can get you killed. Fast Reload perks are subtle but lifesaving, especially on slow-firing rifles. If you’re stocking up using buy Helldivers 2 Super Credits, make sure at least one weapon in your arsenal features this perk.

7. Reduced Recoil

Recoil control improves overall accuracy and shot follow-up speed. This perk is almost mandatory for newer players still getting used to the game's weapon physics.

8. Hollow Point Rounds

While not ideal against armored targets, these rounds absolutely tear through unarmored enemies. They're a top-tier choice during bug-hunting missions.

9. Suppressor

Sometimes staying silent is the best way to survive. A suppressor perk reduces your noise signature, making it easier to avoid triggering enemy patrols—perfect for stealth-oriented squad tactics.

10. Stabilized Aim

This perk helps with weapon sway and makes aiming down sights more efficient, especially useful for marksmen and DMR users. It complements Thermal Sights and other vision-based perks very well.

11. Shock Ammo

Adding an electrical stun effect to your bullets, this perk is great for crowd control and briefly disabling tougher enemies. If you're short on stun grenades, Shock Ammo can fill that gap effectively.

12. Incendiary Rounds

Deal fire damage over time, perfect for finishing off stragglers or weakening groups before they reach your line. Just watch for friendly fire when using this in co-op.

Choosing the right weapon perks in Helldivers 2 is more than just customizing for comfort—it’s about aligning your loadout with your mission goals and your squad's strategy. Perks can make standard weapons feel elite, and elite weapons feel unstoppable. If you're looking to optimize quickly, you can buy Helldivers 2 medals or buy Helldivers 2 Super Credits to unlock gear and upgrades that feature these perks sooner.
