The Boom Cannon fires devastating shots but takes a while to reload. Even the strongest armor is no match for the Boom!
The Boom Cannon is the 6th defense you unlock in Boom Beach. The Boom Cannon deals severe damage to tanks and pierces even the strongest armor. Therefore it’s a great defense against enemy attacks with Tanks and Heavies.
Boom Cannon Offensive Strategies
- Boom Cannons take a while to reload. They can easily be taken with large groups of Troops like the Rifleman.
- Destroy the Boom Cannons with Artillery or Barrage so your Heavies can attack the other enemy defenses.
Boom Cannon Defensive Strategies
- Boom Cannons have a large range, protect as much of your island as possible so attacking Tanks or Scorchers do not stand a chance without taking serious damage.
