"This experimental long range artillery will outrange all but the most far-reaching defenses and rain down with its badaboom shells"


  • The Rain Maker is a Prototroop that fires a salvo of shells at enemy buildings from extreme range. Each shell explodes into shrapnel, dealing further damage, and are capable of triggering Mines, Boom Mines, and Shock Mines, as well as damaging allied troops.
  • The Rain Maker is unlocked for players who have an Armory level of 13 or above and starts 1 level below the Armory level. It can be upgraded using Proto Tokens gained from events.
  • A Rain Maker costs 6 Gunboat Energy to deploy.

Visual Appearance

  • The Rain Maker has the same hull & turret as a Tank, except its main gun is replaced with a golden Mortar-like barrel.

Offensive Strategy

  • You can use the Rain Maker to outrange many defenses, including the Boom Cannon, and can easily strike multiple targets at once. This makes the Rain Maker ideal for dealing consistent damage at range, and is particularly lethal against clusters of structures. Much like Grenadiers, buildings near the primary target can also be quickly whittled down to reduce or eliminate their threat.
    • However, like how Grenadiers work against Cannons and Bombardiers versus Sniper Towers or Mortars, this is a miniscule range advantage. If you have too many Rain Makers, some of them can be pushed into range and may be destroyed immediately.
  • The Rain Maker's shells can trigger Mines around their impact area, which is useful for advancement later in the battle. However, it is not recommended to use them with other shorter-ranged troops, as they can get caught in the blast and be damaged.
  • If positioned correctly, the only normal defenses able to hit the Rain Maker are the Rocket Launcher and Shock Launcher. This means that use of Medics can be helpful to mitigate damage.
    • Due to its vulnerability to the Shock Launcher, it is best to destroy Shock Launchers with Gunboat projectiles before attacking with Rain Makers.

Defensive Strategy

  • As mentioned above, Shock Launchers are an effective defense against the Rain Maker. Additionally, Shock Blasters, Doom Cannons and Grapplers are also effective since they are capable of reaching the Rain Maker. The Lazor Beam can slowly do chip damage as well, but this is generally ineffective
  • Take care to spread out buildings as the Rain Maker's shells and shrapnel are capable of damaging buildings near its intended target.
  • Having a beach base (a base where defensive buildings cover the beach) can prove useful against Rain Makers. Unless they have sufficient Gunboat Energy to flank, the Rain Maker will be unable to fully utilize its advantageous range upon landing on the beach.


  • The March 2020 Update added some Prototype Troops to the game and standardized existing Prototype Troops to fit the Proto Token upgrade system.
  • The Rain Maker's shells are reused assets from high-level Mortars.
  • The Rain Maker has the highest combined shell & shrapnel damage of all troops.
  • While under the effects of the best Troop Damage Masterpiece and 11 Guardians boosted with Power Powder, and LVL 6 Battle Orders the Rain Maker can deliver up to 48,000 combined damage.
