The hurter is an upgrade of the Heater. It has a larger "heater" barrel than its tier two counterpart. It gains damage, range, after burn (after getting away from the object) and loses speed. The same tactics apply as the Heater, but watch out for your reduced movement speed. It is recommended to upgrade movement, as this tank is otherwise as slow as an octo tank. To compensate for this, the Hurter gains a big boost in damage and after burn, allowing it to supress the highest health regen tanks. Note that afterburn only lasts 10 seconds.
