A projectile which releases a cloud of corrosive gas, harmful to both organic and robotic lifeforms.

— Ship Management Terminal

The Orbital Gas Strike is an offensive Stratagem in Helldivers 2 that damages and slows enemies over a large area. The gas released lingers for about 15 seconds before dissipating, during which time all smaller enemies will likely die, and medium enemies will either die or be severely damaged. Larger enemies will take damage, but their health pools are great enough that they are unlikely to perish outright.

Gameplay Tips

  • The gas strike can be placed in advance of a horde to damage and slow them.
  • The gas will slowly spread out after the initial cloud forms, and seems to spread even faster downhill if it's deployed on a slope.
  • If you are being chased, tossing this beacon right at your feet, running for two seconds, then diving away will allow you to just barely avoid the cloud, while ensuring it hits all the enemies on your heels.
  • A single, well-placed Gas Strike can kill all the light bugs that spawn from a Bug Breach, and deliver serious damage to the heavier ones. It is similarly useful for Bot Drops on lower difficulties, though those tend to bring in mostly medium/heavy enemies at higher difficulties.
  • The Gas Strike synergizes quite well with the Orbital EMS Strike, as well as other stunning and slowing effects.
  • While the gas cloud appears to persist for 20 seconds before entirely dissipating, it seems to stop dealing damage as soon as it begins to dissipate, which is after about 15 seconds.
  • A Helldiver can only survive for about 2 seconds while exposed to the gas. If you find yourself choking to death, dive away from the cloud quickly, Soldier!
  • The green gas cloud may become less distinguishable from the surrounding environment, due to certain weather conditions, and/or the fog created by a Spore Spewer.
