The Hailstorm is a Beta ground unit.

Hailstorms barrage enemy troops from behind the safety of their own front lines. Equipped with a mortar launcher, they rain down explosive shells on their targets.[2]


  • Though slow and structurally weak, Hailstorms can deliver a powerful attack from a large distance.
  • Hailstorms can target a specific spot on the ground, effective for clearing out brush or attacking structures that are hidden by Fog of War.
  • Group your hailstorms with other units to keep them protected from close range attacks.
