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.
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.
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.
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.
A Doom Cannon on a player's base could theoretically deal a maximum of 101,430 damage per shot. It would require the best Defensive Building Damage Masterpiece, 9 of the best Guardians boosted with Power Powder, and two Mark III Damage Amplifiers.
