Helldivers 2 is Arrowhead Game Studios' third-person co-op shooter where you fight as expendable soldiers of Super Earth against alien Terminids and robotic Automatons. The game features a persistent Galactic War where every player's missions contribute to liberating or losing planets. With its emphasis on friendly fire, limited ammo, and call-in stratagems, Helldivers 2 captures the satirical military tone of Starship Troopers while delivering genuinely challenging cooperative gameplay.
This guide covers everything you need: core mechanics, the best characters, weapons worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
stratagems
Stratagems are called in by inputting directional codes (like fighting game inputs) on the D-pad. They include orbital strikes, supply drops, turrets, vehicles, and weapons. Each has a cooldown timer and you bring up to 4 per mission. Learning the input codes lets you call them in faster during chaotic combat — muscle memory is essential on Helldive difficulty.
friendly fire
All damage from all sources hits teammates. Orbital strikes, turrets, explosions, and stray bullets kill allies constantly. This is an intentional design feature, not a bug. Communication and positioning are critical — never stand between a teammate and their target, and announce stratagems before calling them in.
extraction
Every mission ends with an extraction phase where you call a Pelican shuttle to a designated point and survive 2 minutes of incoming waves. Missing the shuttle means losing all samples collected. You can call extraction early by reaching the extract beacon. The final waves are always the hardest part of any mission.
sample collection
Samples (Common, Rare, Super) are found throughout missions and used to unlock ship upgrades at the Super Destroyer. You must extract alive with samples or they're lost. Rare and Super samples only appear on higher difficulties (5+ and 7+ respectively). Ship upgrades improve stratagem cooldowns, call-in times, and add new capabilities.
war effort contribution
All players collectively fight a Galactic War on a shared war map. Completing missions on specific planets contributes liberation percentage. Major Orders from High Command set weekly objectives with community rewards. Failing a defense campaign means losing that planet and its benefits until recaptured.
Characters Overview
| Role | Tier | Playstyle | Key Stats |
|---|---|---|---|
| Support | A | Stay near teammates, distribute supplies, and keep everyone alive during extraction. | Medium Armor (stamina balance) > Extra Padding passive |
| Anti-Tank | S | Position behind the team, prioritize heavy targets, and keep heavy weapons loaded. | Heavy Armor with Fortified passive > Extra Padding |
| Crowd Control | S | Frontline fighter clearing chaff enemies while heavies focus big targets. | Light Armor for Sprint Speed > Democracy Protects passive |
| Stealth | B | Avoid patrols, complete objectives silently, call backup only when necessary. | Light Armor < Detection Range reduction |
| Tank | A | Hold the line at objectives, absorb damage, and provide sustained suppressive fire. | Heavy Armor > Fortified passive > Max Armor Rating |
Support (A-Tier): Brings Shield Generator Pack, Supply Pack, and healing stratagems to keep the team alive. The Shield Generator Pack blocks incoming projectiles while letting you shoot out. Support players carry extra stims and handle sample extraction. Essential on Helldive difficulty.
Anti-Tank (S-Tier): Specializes in killing Chargers, Bile Titans, and Hulks with heavy weapons. Recoilless Rifle, Quasar Cannon, or Spear are the primary anti-armor tools. The Expendable Anti-Tank has no cooldown and comes in pairs. Without anti-tank, teams get overwhelmed by heavies on difficulty 7+.
Crowd Control (S-Tier): Uses the Breaker shotgun or Arc Thrower with Eagle Airstrike and Orbital Gatling Barrage to eliminate swarms. The Flamethrower is excellent against Terminid bug breaches. Crowd control is the most needed role since small enemies are the biggest source of team deaths.
Stealth (B-Tier): Uses light armor with Scout passive to reduce detection range, completing objectives without triggering patrols. Works well on Automaton missions where alert chains bring devastating reinforcements. Less viable on Terminid missions where bugs spawn from breaches regardless.
Tank (A-Tier): Uses heavy armor with Fortified or Extra Padding to absorb damage while holding positions. Paired with the Shield Generator backpack and an Autocannon for sustained fire. Anchor the team during defensive objectives and extraction.

Weapons Guide
| Weapon | Why It Matters | Best For |
|---|---|---|
| Breaker | The most popular primary weapon — a semi-auto shotgun with excellent damage per shot and good range for a shotgun. | Crowd Control / general purpose |
| Railgun | A support weapon stratagem that fires a charged shot penetrating medium armor. | Anti-Tank / versatile anti-armor |
| Autocannon | A support weapon with sustained fire capability and medium armor penetration. | Tank / sustained anti-medium armor |
| Quasar Cannon | An energy-based anti-tank weapon with no ammo — it recharges over time (~15 seconds). | Anti-Tank / solo anti-armor option |
| Scorcher | An explosive primary weapon that fires small AoE rounds. | Crowd Control / AoE damage |
Breaker: The most popular primary weapon — a semi-auto shotgun with excellent damage per shot and good range for a shotgun. Effective against all Terminid types except heavy armor. The incendiary variant sets enemies on fire for area denial.
Railgun: A support weapon stratagem that fires a charged shot penetrating medium armor. In unsafe mode, it can one-shot Charger legs but risks exploding if overcharged. Post-nerf it's still strong but requires skill to use safely.
Autocannon: A support weapon with sustained fire capability and medium armor penetration. Requires a teammate to reload the backpack (or slow self-reload). Excellent against Automaton devastators, Terminid hive guards, and light vehicles. 75-round backpack.
Quasar Cannon: An energy-based anti-tank weapon with no ammo — it recharges over time (~15 seconds). One-shots Charger legs and Hulk heads. No backpack needed, freeing you to carry Shield Generator. The most ammo-efficient anti-tank option.
Scorcher: An explosive primary weapon that fires small AoE rounds. Effective against groups and through cover. Slightly dangerous due to friendly fire splash damage but one of the highest DPS primaries available. Unlocked relatively early.
Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Terminid Front | Difficulty 1-9 | Common/Rare/Super Samples, Medals, XP, War Bond progress |
| Automaton Front | Difficulty 1-9 | Common/Rare/Super Samples, Medals, XP, War Bond progress |
| Illuminate Front | Difficulty 1-9 | Unique Samples, special War Bond content, new stratagem unlocks |
| Super Earth | N/A | N/A (lore and narrative context) |
| Creek Sector | Difficulty 5-9 recommended | High Sample density, community bragging rights, Major Order contributions |
Terminid Front: Planets infested with bug-type enemies ranging from small Scavengers to massive Bile Titans. Terminid missions feature bug breaches (reinforcement spawns), organic terrain, and nests that must be destroyed. Fire-based weapons and stratagems excel here.
Automaton Front: Planets defended by robotic enemies including Troopers, Devastators, Hulks, and Tanks. Automaton missions feature fabricators, communication jammers, and long sight-line engagement. Anti-armor and EMP stratagems are critical. Enemies are more accurate at range than Terminids.
Illuminate Front: A third enemy faction added post-launch featuring psychic alien enemies with shield technology and mind-control abilities. Illuminate missions require anti-shield weapons and feature unique mechanics like hallucinations and psychic storms.
Super Earth: The home planet serves as lore background and the war's ultimate stakes. While not a playable mission area, Super Earth's defense status affects galactic war morale and can trigger special Defense Campaign events when threatened.
Creek Sector: A notoriously difficult sector in the Galactic War known for intense Automaton resistance. The community has had extended campaigns trying to liberate Creek planets. It became a meme due to the extreme difficulty and constant pushback.
Tips That Actually Matter
- Dive (press dodge while sprinting) to avoid most attacks including Charger charges, Bile Titan spit, and Automaton rockets. It provides i-frames during the animation.
- Call stratagems on top of objectives to multitask — drop an Eagle Airstrike on a bug nest while simultaneously closing the nest with a Hellbomb.
- Reinforce teammates before calling supply drops — dead players can't grab ammo. Reinforcement beacons bring back all dead teammates.
- Light armor lets you sprint longer and farther for kiting enemies. On Terminid missions, sprint speed often matters more than armor rating.
- Stick together on Helldive difficulty — isolated players get overwhelmed in seconds. Stay within reinforcement beacon range of each other.
- Holding the stratagem input menu pauses the code entry, letting you start the code while sprinting and finish it when you stop.
- Destroy fabricators and nests by throwing grenades inside them rather than calling in stratagems. Saves cooldowns for emergencies.
- Samples persist through death but are dropped on the ground. Mark them with a ping so you can recover them later in the mission.
- Automaton dropships can be destroyed before they deploy troops by shooting their engines with an Autocannon or Recoilless Rifle.
- The SOS Beacon brings random players to your mission. Use it on Difficulty 7+ if your team is struggling — most experienced players respond to SOS calls.
Common Mistakes to Avoid
- Calling orbital strikes on top of the team — always warn teammates before calling in any AoE stratagem, and throw the beacon away from allies.
- Ignoring samples and rushing objectives — ship upgrades from samples provide permanent bonuses that make every future mission easier.
- Standing in front of turret stratagems — AI turrets fire at enemies regardless of friendlies in the way. Always place them behind or beside your team.
- Bringing all offensive stratagems and no support — at least one player needs a Shield Pack or Supply Pack, and someone must have anti-tank.
- Engaging every patrol instead of avoiding them — on higher difficulties, fighting patrols triggers reinforcements that snowball into overwhelming waves.
Frequently Asked Questions
What difficulty should I start at in Helldivers 2?
Start at Difficulty 3-4 (Medium/Challenging) to learn mechanics. Move to 5-6 once you have stratagems unlocked and understand enemy types. Difficulty 7+ requires a coordinated team with assigned roles. Helldive (9) is for experienced groups only.
How does the Galactic War work?
All players share one persistent war map. Completing missions on a planet adds liberation percentage. When liberation hits 100%, the planet is secured. Enemies can counter-attack, requiring defense campaigns. Major Orders are weekly community objectives with rewards for participation.
What are the best stratagems to unlock first?
Orbital Precision Strike (early, versatile), Eagle Airstrike (fast cooldown AoE), Quasar Cannon or Recoilless Rifle (anti-tank), and Shield Generator Pack (survivability). These four cover every mission type and difficulty.
Can you play Helldivers 2 solo?
Yes, but it's significantly harder. The game is balanced for 4 players. Solo players should use lower difficulties (1-5) and bring a combination of offensive and defensive stratagems. Turret stratagems help compensate for missing teammates.
