Summary
- The Boom Cannon is the sixth defense to be unlocked in the game.
- The Boom Cannon is a long-range, single target defense that deals very high damage per shot, but with a slow rate of fire. This makes it particularly effective against troops with high health or a large unit size, such as Tanks or Heavies, but not as much against smaller units like Riflemen.
Offensive Strategy
- When attacking Boom Cannons, be sure to either destroy them upfront with a Barrage or Artillery, or limit your time in range of them without them being shocked. For armies reliant on heavy units, Boom Cannons can potentially ruin an attack.
- Conversely, they can be ignored if massed infantry is used, as their low fire rate greatly weakens their impact on armies centered around smaller units.
- It is possible for Tanks to avoid the shots of a Boom Cannon on the opposite side of the Headquarters unless it is right up against the Headquarters. If there is even one space between the Boom Cannon and the Headquarters, your Tanks will be out of range on the opposite side if you maneuver them correctly.
- However, if you have a large amount of Tanks, some will get pushed within range of the Boom Cannon.
- Because the Boom Cannon targets the nearest troop, you can protect Tanks from Boom Cannons by using Riflemen or Heavies, which have shorter range and will likely walk ahead of the Tanks.
- Critters can do a very good job distracting a Boom Cannon for a period of time especially if the Boom Cannon is protected by few other defenses; this can be an alternative to using Shock Bombs if they become too expensive.
- Boom Cannons need a bit of time to lock onto a target before firing. This timeframe can be used to deploy Shock Bombs to avoid casualties if the response is quick enough.
Defensive Strategy
- Once a total of 4 Boom Cannons are available, it is effective to place them in a diamond or square formation in your base well distanced so that it covers as much of your island as possible.
- On the other hand, you may want to place them all close to your Headquarters to prevent attackers from avoiding certain Boom Cannons entirely simply by attacking the base from the opposite side.
- Though they have relatively high health, it is recommended to place Boom Cannons behind your other buildings, as this allows them to take further advantage of their great range. Having them ahead of your other defenses will increase their vulnerability against smaller enemy units.
Upgrade Differences

- At level 3, the rod on top of the barrel becomes larger and two rods are seen behind the shield.
- At level 4, the base increases in size.
- At level 5, a wire is seen running along the base of the Boom Cannon.
- At level 6, the Boom Cannon gains a thicker barrel and slightly darker colored plating and barrel. The shield increases in size. Vents are cut in on the side of the weapon. The general color scheme turns to a reddish-brown.
- At level 7, metal reinforcements are seen on top of the concrete base.
- At level 8, a white light is seen at the back of the Boom Cannon.
- At level 9, the wheel on the back of the Boom Cannon is replaced by a hatch.
- At level 10, the Boom Cannon gains a metal base, an even thicker barrel, tubes at the back, and darker colored plating. The back handwheel disappears. The white light is replaced by a green one and the shield becomes larger.
- At level 11, the Boom Cannon gains a heavily armored base. Red metal plates are seen on it and an exhaust vent is added at the end of the tubes.
- At level 12, the base gets more metal reinforcements.
- At level 13, the metal rod on top of the barrel is replaced by a cylinder with vents cut in it.
- At level 15, the Boom Cannon's barrel is much larger, and it gains steel ventilation on top of it, as well as a few layers of red metal plates between the steel ventilation plates and the barrel. A wire can be seen connecting the barrel to the back of the Boom Cannon, as well as a fiery glow within the barrel itself.
- At level 16, more tubes appear at the back. The green light moves to the top and the loading hatch becomes larger.
- At level 17, the base of the Boom Cannon is reinforced with wooden boards.
- At level 18, the wooden base of the Boom Cannon is replaced with white stone.

Trivia
- The Boom Cannon is based on the M-Gerät (Big Bertha), a German siege howitzer used in World War 1.
- When it fires, the Boom Cannon's barrel seems to retract in a similar manner to the Cannon. However, the handwheel does not.
- The Boom Cannon's shell appears to create an impact crater similar to that of Artillery, despite not inflicting splash damage.
- While under the effects of the best Defensive Building Damage Masterpiece, 11 Guardians boosted with Power Powder, and four Mark III Damage Amplifiers, a Level 19 Boom Cannon will deal 63642 damage per shot.
- The upgrade costs of the level 14, 16, 17 and 18 Boom Cannon are the same as the upgrade costs of the level 13, 14, 15 and 16 Rocket Launcher respectively, with the exception that the resources are swapped for all levels except the first.
- The Boom Cannon has the most health of all the defenses.
- The Boom Cannon has the most expensive max upgrade cost for a defensive building, costing 20,210,000 in total resources for the last level.
