Houndoom

 is a Tier 5 Tank that upgrades from Annihilator, MX-Gun, Devastator and Steamroller at level 60.

Design
The appears to be an Annihilator with a slightly thinner barrel in it. However, unlike Annihilator, its big barrel is not the full width of the tank. Its big and small barrels are proportioned similarly to Hunter.

Technical
Being a Destroyer Hunter, both of its bullets are quite powerful. Like other Hunters, the smaller barrel fires first, quickly followed by the larger one.
