Few weapons in Helldivers 2 embody the overwhelming firepower of Super Earth quite like the Quasar Cannon. Designed as a high-impact anti-armor solution, this energy-based heavy weapon is a favorite for players who want to erase the toughest enemies on the battlefield—or complete demanding Personal Orders that require precision and patience.

This guide explains how to unlock the Quasar Cannon, how it functions in combat, and the best ways to use it against Terminids, Automatons, and Illuminate forces. Everything below is written entirely fresh and original, while staying accurate to the game’s mechanics.

What Is the Quasar Cannon?

The Quasar Cannon is a single-shot, energy-based anti-tank weapon built for deleting heavily armored targets in one devastating blast. Instead of using traditional ammunition, it relies on an internal energy charge, giving it unlimited ammo at the cost of charge and cooldown management.

This makes it ideal for players who prefer deliberate, high-impact shots rather than sustained fire.

How to Unlock the Quasar Cannon

The Quasar Cannon is unlocked through the LAS-99 Quasar Cannon Stratagem.

Unlock Requirements

• Available at Level 18

• Purchased from Ship Management → Engineering Bay Stratagems

• Costs 7,500 Requisition Slips

Once purchased, the stratagem becomes permanently available on your account.

Equipping the Quasar Cannon

After buying it:

1. Open your loadout

2. Navigate to Supply Stratagems

3. Equip the LAS-99 Quasar Cannon

Stratagem Input Code

To call it down during a mission, enter the following input:

• Down → Down → Up → Left → Right

Calling Down the Quasar Cannon

Once deployed, the Quasar Cannon behaves like other heavy weapons—but with a few unique traits.

Deployment Details

• Drop time: ~7.75 seconds

• Cooldown: 410 seconds

• Call-in limit: Unlimited (cooldown permitting)

Because it has infinite ammo, you only need to call down another Quasar Cannon if:

• You die and can’t retrieve it

• The weapon is left too far behind during extraction or repositioning

How the Quasar Cannon Works

Understanding its firing cycle is essential to using the Quasar Cannon properly.

Core Mechanics

• Charge time: ~4 seconds

• Firing mode: Single-shot

• Reload time: ~15 seconds (automatic)

• Ammo: Infinite

After firing, the cannon automatically begins recharging. You’re free to:

• Swap weapons

• Reposition

• Call stratagems
  while the recharge happens in the background.

This design rewards smart timing rather than aggressive spamming.

Best Targets for the Quasar Cannon

The Quasar Cannon is classified as an Anti-Tank weapon, meaning it excels against armored enemies and structures—but struggles against light infantry.

Ideal Enemy Targets

Use the Quasar Cannon against:

• Hulks

• Chargers

• Bile Titans

• Automaton Tanks

• Factory Striders

• Harvesters

• Stingrays

These enemies often fall in one well-placed shot, especially when weak points are exposed.

Destroying Enemy Structures

The weapon is also highly effective against:

• Automaton Fabricators

• Mortar Emplacements

• Shrieker Nests

• Terminid Nests

• Enemy Dropships and static defenses

One shot can often remove an entire threat from the map, saving time and resources.

What Not to Use It On

The Quasar Cannon is not designed for:

• Swarms of light infantry

• Fast, disposable enemies

• Close-range panic situations

Using it on fodder enemies wastes its long recharge cycle and leaves you vulnerable during the reload window.

Best Missions for Quasar Cannon Personal Orders

If you receive a Personal Order requiring Quasar Cannon kills, mission selection matters.

Recommended Setup

• Enemy faction: Automatons

• Mission duration: 40 minutes

• Map type: Open terrain with long sightlines

Automaton units tend to:

• Engage from range

• Rely on armored elites

• Guard objectives with heavy units

Because the Quasar Cannon has no damage drop-off, long-range shots are just as lethal as close ones—making Automaton missions ideal for stacking kills safely.

Advanced Tips for Quasar Cannon Use

• Fire from elevated terrain whenever possible

• Let teammates handle crowds while you focus on priority targets

• Use terrain for cover during recharge windows

• Pair with mobility armor or stamina perks to reposition quickly

• Treat each shot as a “problem solver,” not a panic button

Mastery comes from patience, not aggression.

Final Thoughts

The Quasar Cannon isn’t about constant fire—it’s about decisive impact. When used correctly, it can trivialize the toughest enemies Helldivers 2 throws at you, turning armored nightmares into scrap with a single charged shot.

If you enjoy methodical, high-reward gameplay and want one of the most satisfying anti-tank weapons available, the Quasar Cannon is absolutely worth unlocking and mastering.
