"Shoots a Doom Ray that destroys most targets outright. Very slow rate of fire."

Mark 1 Mark 2 Mark 3


  • The Doom Cannon is a Prototype Defense that is built in the Weapon Lab.
  • Like all Prototype Defenses, it will only last 7 days after it is placed on your base.
  • This defense has a very high damage per shot. Only Scorchers are likely to be able to survive a shot from the Doom Cannon.
  • It has a very small splash radius.

Offensive Strategy

  • Like the Boom Cannon, the Doom Cannon fires very slowly and thus is very vulnerable to massed infantry attacks. This means Riflemen and/or Zookas or a Warrior attack will be your best chance to deal with this defense.

Defensive Strategy

  • Try to place Doom Cannons away from Boom Cannons to stop attackers from disabling multiple high damage-per-shot defenses with one Shock Bomb.
  • Place Doom Cannons behind splash defenses. This allows them to shoot many times, while at the same time being protected from massed infantry.
  • Similar to the Boom Cannon, the Doom Cannon is very effective in damaging high-health troops like Tanks and Scorchers.

Version Differences

  • At Mark I, the Doom Cannon appears as a small glowing turret on a red-and-black stand in a pit lined with black railing. A red box and some wires are connected to it.
  • At Mark II, the Doom Cannon has a more refined pit wall and red and black covering around the railing.
  • At Mark III, the Doom Cannon has more improved covering around the rail, and the lower portion of the stand turns red. A wire is added at the base. The red box is replaced with two gray pipes. A third long pipe also appears at the front.


  • The Doom Cannon has the highest damage per second and damage per shot of all the defenses in the game.
  • The Doom Cannon could theoretically deal 42,840 damage per shot. It would require the best Defensive Building Damage Masterpiece and 9 of the best Guardians.
    • If all ten Statues were boosted with Power Powder, the Doom Cannon would be doing an absurd 69,930 damage per shot.
      • If all ten Statues were boosted with Power Powder and the Doom Cannon was next to a mark III Damage Amplifier, the Doom Cannon would do a mind-blowing 85,680 damage per shot, which is almost twice a max-level Scorcher's HP.
      • But then again, a Max level Scorcher with fully boosted max Magma troop health statues(1 Masterpiece+9 Guardians) has a whopping 181,460 health, which can withstand 3 of the Doom Cannon's shots.
