"Charges to fire a powerful, explosive energy burst. Has a long cooldown period after firing."

The LAS-99 Quasar Cannon is one of the stratagems available to the player. The weapon is similar to the LAS-98 Laser Cannon, but rather than firing a sustained beam, it charges up a single shot of explosive energy with the power of an EAT-17 Expendable Anti-Tank round.

The Quasar Cannon has infinite ammo. It does not have any magazines, nor heat sinks that have to be replaced, and is capable of safely cooling itself with no threat of overheating. However, it has a particularly long cooldown period between shots, and it cannot be used while it is still venting heat.

Stratagem Code[]

Players must enter the following sequence, using the default Ctrl+WASD keys or the controller D-Pad in order to call down this single-use Stratagem during a mission:

Stats[]

  • Call-in Time: 8 seconds
  • Uses: Unlimited
  • Cooldown Time: 480 seconds (8 minutes)

Gameplay Tips[]

  • The LAS-99 has anti-tank level penetration, much like all the anti-tank launchers.
  • Like other laser weapons, the Quasar Cannon will continue to cool down when not equipped or dropped, giving the user the freedom to use other weapons during its recharge period.
  • The LAS-99 can destroy bug holes and fabricators. With the LAS-99, you don't need to shoot into the vent of a fabricator. The shot can hit the fabricator anywhere and will destroy it.
  • Unlike other laser weapons, the Quasar Cannon does not feature any ammo. Instead, it charges up and cools off for each shot. This gives the Quasar Cannon far greater staying power than most other heavy weapons.
  • The main weakness of the Quasar Cannon is its 3 second charge time before a shot, followed by its long 15 second cooldown, making it difficult for Helldivers to dispatch large number of heavily armored enemies attacking simultaneously.
  • When targeting weak points of heavily armored enemies like Hulks and Chargers, it is recommended aim down sights rather than from third person, the scope has a substantial level of zoom and can make all the difference when trying to kill a distant Heavy before it reaches you.
    • This also applies to enemies that may not have heavy armor or small weak points but are nearly constantly moving like Dropships, Gunships and Stalkers.
  • It also has near-infinite range and no bullet drop, though even stationary targets can be missed with the slightest amount of weapon sway. It is advised to fire while prone.
  • During defense scenarios, one way to get around the Quasar cannon's long cooldown is to deploy two cannons, switching between them per shot.

Notes[]

  • As of Patch 01.000.400 the quasar cannon will cooldown 2.5 seconds slower on planets with extreme heat, and 2.5 seconds faster on planets with extreme cold.
  • Current production models of the Quasar Cannon (since Patch 01.002.201) have a faulty charging trigger. The weight of the trigger when the weapon is stowed on one's back is sufficient to charge the weapon after it completes its cooldown cycle, yet not enough to cause a self-fire. You will have to use it near instantaneously after swapping or else it will decharge and you will have to charge it manually once more, but the "BUG" will return after firing manually.
