Candy bazooka is the only artillery weapon (along with artillery cannon) that has a clip size larger than 1 and can fire multiple explosive projectiles. Candy bazooka is like a slightly weaker version of artillery cannon. I wouldn't use candy bazooka as a spar/primary weapon. Using it as a finishing weapon or for bases is effective. The main use of this weapon is the explosive effect. Don't be afraid to aim for walls that are near enemies. The splash damage is deadlier than you think.
