Flank Swarm

The Flank Swarm is a tier 3 tank that branches from Basebrid and Flank Guard at level 30

Design
It has the normal Basic front barrel but has a tiny trapezoidal barrel on its back.

Technical
Upgrading to the Flank Swarm gives you a uncontrollable swarm barrel. The barrel constantly produces swarm drones that disappear after a few seconds (this can be increased with bullet health upgrades).

The Flank Swarm branches to the following:
 * Fortress
 * Flank Cruiser
 * Hybrado

As the Flank Swarm

 * The drones can protect your back when your fighting 1v2
 * When an enemy is low health and your bullets can't hit, the drones can usually finish them

Against the Flank Swarm

 * The drones cannot be controlled and will not always attack what you want it to attack.
 * The drones don't have a long range and sniper tanks can keep a distance to be safe from your drones.
