Swarmers are a powerup that appear in the BattleTanx Series. Unlike most weapons, these unguided rockets would curve, allowing them to hit a single target with multiple rockets at a certain range, or even shoot them around corners.

Three missiles are fired off. One goes straight and the other two initially curve slightly away, but given space will go across to each others side. At close range, all three missiles can be used on one tank and cause heavy damage. A special attack (which uses all of the chosen weapon and is activated by pressing the weapon fire and weapon switch button simultaneously) can be initiated if one has fifteen or more swarmers. The special fires all of the swarmers rapidly in a more spread out fashion.
