In Helldivers 2, surviving enemy waves isn’t just about having powerful weapons—it’s about deploying the right stratagems at the right time. Combining stratagems effectively can turn a losing defense into a quick cleanup operation. Whether you're fending off Automatons or Bugs, these combos will help you handle swarms like a true veteran. Here are eight stratagem combos that consistently deliver results on the battlefield.

1. Orbital 120MM HE Barrage + Static Field Conductors

This is a staple combo for locking down a high-traffic zone. The barrage eliminates clustered enemies in an instant, while the static field slows reinforcements just enough for your squad to finish them off. Use it near objectives when you're about to get swarmed.

2. Eagle Cluster Bomb + Machine Gun Sentry

Fast and brutal, this combo is perfect for thinning out large groups quickly. Drop the cluster bomb first, then place your sentry behind cover. The sentry provides sustained suppression while any survivors from the initial strike are cleaned up.

3. Autocannon Sentry + Orbital Gas Strike

If you're facing enemies that tend to bunch up or don’t die easily, this is a reliable answer. The gas weakens enemies gradually, while the autocannon mows down anything that pushes forward. It’s particularly effective against the Bug faction's heavier units.

4. Railgun + Eagle Strafing Run

For players who prefer a more mobile role, pairing the railgun with a strafing run offers a balanced offense. Take out priority targets with the railgun, and use the strafing run to scatter incoming groups or buy time for repositioning.

5. Mortar Sentry + Incendiary Mines

This combo shines during defense missions. Set up the mines in choke points and let the mortar rain down suppression. Enemies that survive the blasts often walk right into fire traps. It's also a good setup for missions where wave timing is predictable.

6. Orbital Laser + Shield Generator Relay

Sometimes, the best defense is a flashy offense. Activate the laser to keep lanes clear while the shield generator gives you and your team enough time to revive, reload, or call in reinforcements. It’s a higher-tier combo but extremely effective when outnumbered.

7. Eagle Napalm Airstrike + Anti-Personnel Minefield

Great for wave anticipation. Lay the mines in advance, then drop the napalm slightly ahead of the mine line. Enemies caught between both have little chance to escape. It works especially well in urban or narrow-map scenarios.

8. Thunderer Smoke + Orbital Precision Strike

If you're running stealth or recon builds, this combo lets you control the battlefield without direct confrontation. Use the smoke to disorient or block sightlines, then follow up with a pinpoint strike on high-value targets. Ideal for coordinated squads that value efficiency over chaos.

Stratagem efficiency becomes even more critical in higher-difficulty missions where each mistake costs lives—and potentially your objective. Building the right loadout isn’t just about power; it’s about synergy.

Whether you're grinding for resources or trying to optimize your loadout, many players look for ways to upgrade faster. Some even explore options like Helldivers 2 Super Credits for sale to speed up progress. If you're aiming to buy Helldivers 2 Super Credits, platforms like U4GM are often discussed among the community for convenience and service reliability. Just remember to always make informed choices when it comes to third-party services.

Mastering these stratagem combos can significantly increase your squad's survivability and mission efficiency. Try mixing and matching based on your team’s roles, and you'll find new ways to dominate the battlefield every session.
