For players looking to control the battlefield, the Airdropped Anti-Personnel Mines stratagem is a fundamental tool. This guide breaks down its functionality based on common gameplay experiences, aiming to answer the practical questions most players have.

How Do You Unlock the Minefield Stratagem?

In general, you unlock this stratagem by completing all missions on its designated reward planet. This is typically a lower-difficulty planet, set between difficulty 1 and 3. It's one of the earlier stratagems you can acquire, making it accessible for new divers who want to start specializing in area denial.

What Exactly Does It Do and How Do You Call It In?

When called, the stratagem drops a carpet of self-arming, self-burying mines in a strip perpendicular to the direction you are facing when you throw the beacon. The sequence to input on your d-pad is: Down, Right, Left, Up. The mines scatter randomly within this area. Anything that walks over them—enemy or ally—will trigger them. They arm after a short delay once buried, and then explode a moment after being triggered, which gives lighter enemies a small chance to move through if they are fast. It's crucial to remember that these mines are indiscriminate; they will down a fellow Helldiver just as easily as a bug.

Is Upgrading the Mines Worth It?

Absolutely. The upgrade path is straightforward and significantly changes the stratagem's role.

• Mk 1: The basic version. You can call it in five times per mission.

• Mk 2: For 1 Research Point, this increases your "supply priority." This simply means the number of times you can call it in per mission doubles from 5 to 10.

• Mk 3: For 2 more Research Points, this is the key upgrade. It transforms the mines from Anti-Personnel to Anti-Tank. The stratagem's name changes to Airdropped Anti-Tank Mines. The mines visually change to black discs with red lights and are capable of crippling heavy armor. A single mine can detrack a Cyborg IFV and severely damage or destroy most medium armored targets.

What Are the Key Gameplay Tips and Limitations?

Most players use this stratagem for defense and area denial. Here’s how it works in practice:

• Defensive Setups: The most common use is to lay minefields around objectives you must defend, like launch pads or geological survey stations. This creates a protective barrier that deals with enemy patrols automatically.

• Funnel and Kill Zones: You can use them to block or mine specific chokepoints on the map, funneling enemies into your team's main line of fire.

• The Shared Limit: This is the most critical mechanic to understand. Only five sets of these area-denial stratagems can exist on a map at once for your entire squad. This pool includes Airdropped Anti-Personnel/Anti-Tank Mines, Airdropped Stun Mines, and the Anti-Personnel Barrier (if you have the DLC). If a sixth set is called, the oldest set on the map will vanish. This means teams need to coordinate; if everyone is spamming minefields, you will constantly erase each other's defenses.

• Trigger Warnings: The mines can be set off by grenades, so avoid throwing grenades into your own active minefields. While Illuminate units hover, they can still trigger mines if they pass directly over them. Visually, the lethal mines have a red light, while the non-lethal Airdropped Stun Mines have a white light—a good distinction to spot in the heat of battle.

• Strategic Consideration: Because of the shared limit, many experienced teams prefer to dedicate one player to the role of area-denial specialist. This prevents the wasteful cycling of mines. For those looking to optimize their loadout without excessive grinding, some opt to buy Helldivers 2 items easily on U4N to acquire the necessary resources for upgrades like the vital Mk 3 anti-tank conversion.

Should You Use Anti-Personnel or Anti-Tank Mines?

This choice depends entirely on the enemy faction and mission type.

• Against the Terminids (Bugs): The basic Anti-Personnel mines are very effective for clearing out small to medium bugs like Hunters and Warriors, especially when defending a point. For higher difficulties where Chargers and Bile Titans appear, the Anti-Tank upgrade becomes essential for dealing with the heavier threats.

• Against the Cyborgs: The Anti-Tank upgrade is generally recommended here due to the prevalence of armored units. A well-placed anti-tank minefield can stop a patrol of IFVs in its tracks.

• Against the Illuminate: Their lighter, floating units make Anti-Personnel mines less reliably effective. The shared stratagem limit is often better used on other support tools, though Anti-Tank mines can still destroy their obelisks and tripods.

In summary, the Airdropped Mines are a powerful defensive tool with a crucial squad-wide limitation. Effective use requires thoughtful placement, team coordination regarding the five-set limit, and choosing the right upgrade for your enemy. When used correctly, they can quietly secure an entire flank, allowing your squad to focus firepower elsewhere.
