Fanon:Burrower (lvl 45)

The Burrower is a special tank that is only available in Stories of Life part 2 or when defeating 300 Green runners. It is able to burrow under the map (see Stories of Life) in order to cloak itself. When not in Stories of Life, it will push shapes around when burrowed.

Mechanics
It is essentially a gunner mixed with a Booster that can burrow. The Burrow spike on the front is a special weapon which, when un-burrowing, will spike anything in its range. It can also be used to ram things. This tanks's burrow ability allows it to not be attacked by anything when burrowed, allowing it to absolutely rek tdm.

Appearance
It looks like a smaller-than-usual tanks with a spike at the front and three small gunner barrels at the back.
