Tank Bots were large vehicles that could fire rockets or short streams of flame from their cannons depending on how close an enemy was. Heavily armored and imposing, a successful way for a player to bring one down was to remain out of its range and use a strong long range weapon like the Flux Rifle to bring it down.
Tank bots had strong armor and strength with long range. Only two ever appeared, in Up Your Arsenal, one in the Deathcourse's Gauntlet, and one in Metropolis. While the one in the Gauntlet was easily noticeable and dispatched, the one in Metropolis was significantly harder as it had the element of surprise and far more powerful missiles. It might have been the Tyhrranoids answer to the Turboslider.
