The Fallen Auto Tank is a boss that was added on February 2, 2019.
Fallen Auto Tank has a gray circle base with four auto-turrets evenly spread around it.
The Fallen Auto Tank shoots strong bullets with high penetration and speed from its turrets. Only two auto-turrets can be locked on a single player. The Fallen Auto Tank moves at a low speed, and it does not auto spin, similarly to it’s tank counterpart, the Auto-Tank.
Spawns by a randomizer.
The Fallen Auto Tank has high firepower, and the auto turrets can lock on multiple enemies at once (it only follows one tank). Its bullets have high damage and penetration while having some spread. Most low RoF tanks just cannot penetrate the bullets of Fallen Auto Tank, while minions will just not be able to stop all the bullets. Fallen Auto Tank moves too slowly speed to ram into pillboxes or traps, so while it will approach the player's traps, they will disappear before dealing damage to the Fallen Auto Tank. This means that low RoF tanks, drones, trap, and minion tanks are not effective against Fallen Auto Tank.
The most effective tanks that can easily kill Fallen Auto Tank are bullet spammers. A heavy wall of bullets will penetrate most of the Fallen Auto Tank's bullets, while a small part of your bullets will land on Fallen Auto Tank and deal some damage to it. In order to eliminate Fallen Auto Tank as a bullet spammer, you should move in a left-right pattern, and sometimes shoot not in the Fallen Auto Tank's bullets, but at the boss itself.
