Underground missions in Helldivers 2 can feel like a completely different game compared to surface-level operations. Instead of wide open battlefields, you’re funneled into tight corridors with constant enemy pressure, limited visibility, and fewer opportunities to escape. If you’re struggling to clear these missions, here are some tips to help you and your squad survive the chaos.

Understand the Underground Layout

Unlike open missions, underground levels are full of bottlenecks. The map design forces players into chokepoints where enemies spawn endlessly. Always move as a group, and avoid wandering into unexplored areas alone. If you push forward without support, you risk getting overwhelmed.

Choose the Right Weapons and Stratagems

Underground missions reward close-range combat efficiency. Shotguns, flamethrowers, and SMGs excel in tight corridors, while explosives like grenades and rocket launchers can clear swarms quickly. Stratagems that provide crowd control or defensive cover—such as turrets and supply packs—are crucial. Since space is limited, coordinate with your squad so you don’t block pathways with poorly placed equipment.

Manage Light and Visibility

Dark tunnels make it hard to spot enemies until they’re on top of you. Flashlights and flares become surprisingly valuable tools underground. Assign at least one squad member to deploy flares regularly, as this helps with spotting ambushes before they happen. Staying aware of your surroundings is half the battle.

Team Coordination Matters

Communication is the key to surviving underground missions. Assign roles before entering: one player handles heavy weapons, another manages support stratagems, while others focus on clearing enemies. If your squad lacks balance, the mission becomes far more difficult. Playing with a coordinated group often makes these missions feel more manageable than tackling them solo.

Resource Management

Ammo and reinforcements are limited, and running out mid-mission is one of the fastest ways to fail. Underground areas don’t give much breathing room, so plan supply drops wisely. Dropping them in narrow hallways can block movement, so aim for larger rooms when possible.

Progression and Preparation

If you find underground missions especially punishing, it might help to upgrade your loadout first. Players often look for ways to strengthen their arsenal or improve their builds. Some choose to buy Helldivers 2 medals to speed up Warbond unlocks or buy Helldivers 2 items that give them a wider range of tactical options. While not strictly necessary, these resources can make a big difference in overall survivability.

Beating underground missions in Helldivers 2 isn’t just about raw firepower—it’s about teamwork, preparation, and smart use of resources. Go in with a clear strategy, maintain constant communication with your squad, and don’t be afraid to retreat and regroup when overwhelmed. With practice, what once felt like a nightmare tunnel crawl will start to feel like just another chance to spread managed democracy underground.
