Boomer-2

 is a Tier 5 Tank that upgrades from Boomer and Builder-2 at level 60.

Design
The has two Boomer turrets on either side of the tank. They each look identical to Boomer, but scaled down to about half normal size.

Technical
The boomerangs this tank fires act mostly like normal boomerangs, with some extra strange behavior likely caused by interaction with the turret mechanics.

Firstly, no matter the orientation or target of the individual turret, the boomerang will always attempt to go to the position of your mouse, even if you are not firing. While this does eliminate the ability inherent to most Auto-2s to focus on multiple targets, this gives you surprisingly good focused fire for a tank of that branch.

Secondly, the turrets will both fire no matter where you are aiming and firing. They will both fire and as stated above, will both send their boomerangs to your mouse.
