How to Unlock the Quasar Cannon

The Quasar Cannon is available as the LAS-99 Quasar Cannon Stratagem. Players can unlock it through the Engineering Bay Stratagems section in Ship Management. To purchase it, you must reach Level 18 and spend 75,000 Requisition Slips.

After unlocking it, the weapon can be equipped in your loadout under the Supply Stratagems category. To deploy the Quasar Cannon during a mission, enter the Stratagem code:

Down, Down, Up, Left, Right

Once activated, the weapon takes approximately 7.75 seconds to be delivered. The Quasar Cannon has a 410-second cooldown, but it can be called in repeatedly as long as the cooldown has finished. Since it features infinite ammunition, you typically only need to request another one if you lose it after dying or leaving it behind.


How to Use the Quasar Cannon

The Quasar Cannon is a high-powered, single-shot energy weapon designed primarily for destroying heavily armored targets. It requires about 4 seconds to fully charge before firing and has a 15-second automatic recharge time after each shot. Because the reload process happens automatically, players can safely switch to another weapon while waiting for the cannon to recharge.

Best Targets

As an Anti-Tank weapon, the Quasar Cannon performs best against enemies with Medium, Heavy, or Tank Armor. It is not recommended for dealing with basic infantry units, as its slow firing rate makes it inefficient against smaller enemies.

The weapon is especially effective against powerful threats such as:

  • Hulks
  • Chargers
  • Bile Titans
  • Tanks
  • Factory Striders
  • Stingrays
  • Harvesters

Destroying Enemy Structures

In addition to eliminating armored enemies, the Quasar Cannon is extremely useful for destroying fortified enemy structures and bases. It can quickly take down:

  • Mortar Emplacements
  • Shrieker Nests
  • Fabricators
  • Enemy Nests
  • Enemy Ships


Best Strategy for Personal Orders

If you're working on a Personal Order that requires 45 kills using the Quasar Cannon, Automaton missions are generally the most efficient choice. Missions with open terrain and longer timers, such as 40-minute operations, provide the best opportunities to maximize your kills.

The Quasar Cannon benefits from zero damage drop-off, allowing you to safely eliminate targets from long distances. Since Automaton forces frequently deploy heavily armored units and often engage from range, they are ideal targets for this weapon.


By mastering the Quasar Cannon, players can handle some of the toughest enemies in Helldivers 2 with precision and efficiency. With proper positioning and timing, this weapon becomes one of the most reliable tools for spreading managed democracy across hostile worlds.
