- Double Cannons fire rapid bursts of cannonballs at ground troops, with four shots per volley.
- Double Cannons are only available in the Builder Base. They are unlocked at Builder Hall 2.
- The Master Builder can gear up a Cannon in the Home Village which will allow the cannon to shoot similarly to the Double Cannon. This requires Cannon at at least level 7 in the Home Village and a level 4 Double Cannon in the Builder Base.
- While Double Cannons do high damage per second, they have a short range and cannot attack air troops.
