When the gun is fired, like the name implies, it fires a swarm of bees.
It was designed by Jimmy Torbitson in order to ward off overexcited fans from attacking Pierce without killing them. The Swarmitron also is used in an unsuccessful attempt to calm Johnny Tag. Like the weapons from the Gangstas in Space DLC, in can only be used in one mission.[1]
Trivia[]
On the Swarmitron, is a beehive which acts as the ammo and a bee's stinger in the gun's back.
Although the Swarmitron is not an Explosive weapon, but a Special weapon, when someone is killed with the gun, the game marks it as an Explosive Kill.
The Swarmitron bears many similarities to the Sonic Boom. Both weapons are chargeable with have infinite ammo, fire a single shot before needing to be reloaded, and occupy the special-class weapon slot. However, a fully charged Swarmitron blast is not likely to be lethal whereas a fully charged Sonic Boom blast is likely to be lethal.
