- — In-game description.
The Hailstorm is unlocked at level 49.
The Hailstorm can also be unlocked prior to the normal level of unlock if the player was awarded the Thunder variant, which is available for free to all players who have launched and played Call of Duty: Black Ops III at least once. The Thunder variant was once available for purchase for 4000 Salvage, however this ability was removed in the January 13th, 2017 patch for PS4/Xbox One and the 20th January, 2017 patch on PC.

The Hailstorm is available in Zombies in Spaceland as a wall weapon in the starting room for 500 points. It is available for customization at level 2. The Hailstorm is a point weapon, useful for accumulating headshots, and even dealing with small groups of zombies.
Hollow Point adds a sizable headshot bonus to the already high factor, making headshot multikills a viable strategy. Dual Wield, while a seemingly effective choice, is indeed powerful in single-digit rounds, but quickly becomes obsolete in higher rounds.
When upgraded via the Pack-a-Punch Machine, the Hailstorm becomes the Tropical Thunder, gaining increased damage, a larger magazine, and more reserve ammo. It increases the magazine size to a whopping 28 rounds, and converts the primary fire rate to a four-round burst.
