Underground missions in Helldivers 2 are some of the most intense experiences the game has to offer. The cramped tunnels, limited visibility, and relentless waves of enemies make them feel entirely different from surface operations. Whether you’re grinding for resources or looking to challenge your squad’s coordination, going underground requires a careful mix of strategy, loadout preparation, and smart teamwork.

1. Prepare the Right Loadout

Underground maps are often narrow and filled with chokepoints, which makes area-of-effect weapons and crowd-control tools much more valuable. Flamethrowers, shotguns, and explosives excel here. You’ll also want to bring support stratagems that fit the environment. Turrets can cover corridors, while supply packs ensure your team doesn’t run dry on ammo.

2. Control the Chokepoints

Most underground encounters funnel enemies through tunnels. Positioning is everything—set up your fireteam so one or two players hold the line while others support from behind. This formation prevents you from being surrounded and maximizes your firepower. Just remember that explosives can backfire in tight spaces, so be careful with grenades.

3. Keep Moving Between Objectives

Unlike surface missions where open ground allows for flexible movement, underground missions often punish players who linger too long. Enemies spawn endlessly, so staying in one spot can overwhelm you. Once you’ve cleared an objective, regroup and push forward rather than farming kills.

4. Communicate Constantly

Underground environments amplify the need for coordination. You won’t have much visibility ahead, so calling out enemy positions, tunnel directions, or stratagem drops becomes essential. Even experienced squads can fall apart if communication breaks down, especially when swarmed by bugs or bots in the dark.

5. Balance Risk and Reward

These missions are excellent for farming resources, but it’s important not to get greedy. If your squad is running low on ammo or stratagem cooldowns, sometimes it’s smarter to extract early than to risk a full wipe. Completing even partial objectives is often more rewarding than losing everything in a last stand.

Underground missions highlight the cooperative core of Helldivers 2. They demand tighter teamwork and smarter resource use than most surface battles. For players looking to progress faster, these missions are also a great way to build up resources.
