Summary
- The Doom Cannon is a Prototype Defense that is built in the Weapon Lab.
- Like all Prototype Defenses, it will only last for a certain amount of time after it is placed on your base.
- The Doom Cannon is a long-range point defense with a very small splash radius, average fire rate and extreme damage. Only Heavy Choppas, Incinerators, Mechs, Scorchers, or Pvt. Bullit are likely to be able to survive a single hit.
Offensive Strategy
- Like the Boom Cannon, the Doom Cannon's greatest advantage is its range and damage, as it can easily pick off anything it hits while attackers fight their way through, although it is still vulnerable to many smaller units, as there's likely enough spacing for them to avoid its splash. Distracting them with Critters is a valid option, although other enemy area defenses can render this ineffective.
- Various sources of shield points, such as Dr. Kavan's Ice Shields, the Crystal Shield Projector and Bomb & Shield's ability can be used to dismiss one attack from the Doom Cannon, as all excess damage dealt in a single hit is negated.
- Pvt. Bullit's ability to limit damage allows him to effectively tank Doom Cannons with little trouble.
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. This works well due to their high range as they will still be able to support other defenses from deep within your base.
- It is likely that attackers will surround the Doom Cannon with Critters to mitigate its splash radius. To combat this, place the Doom Cannon under the protection of area damage defenses such as Flamethrowers and Mortars to wipe out distractions quickly and allow it to focus on destroying enemy troops. There isn't much that can be done against Shock Bombs, however, so its contribution to your defense is dependent on if the attacker perceives it as a priority threat or not.
- Similar to the Boom Cannon, the Doom Cannon is very effective in destroying high-health troops like Tanks and Scorchers, but despite their splash radius and range, can still become vulnerable to enemy swarms if given the chance.
Version Differences
- At Mark I, the Doom Cannon appears as a small glowing turret on a red-and-black pillar 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 conduits. A cable also appears at the front.
Trivia
- 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 162,855 damage per shot, barring any Tribe boosts. It would require the best Defensive Building Damage Masterpiece, 12 of the best Guardians boosted with Power Powder, and five Mark III Damage Amplifiers.
- In practice, however, the Doom Cannon can only cause 147,105 damage because one of the five Protodefense Slots is reserved for the Doom Cannon itself.
