The Auto 3 is a tank that was released unnamed on August 2, 2016, and was later named on August 5, 2016. It is one of the four current upgrades from the Flank Guard and can be selected at Level 30. It may further upgrade into the Auto 5 or the Auto Gunner.
The Auto 3 features a circular body with three Auto Turrets spaced at 120-degree angles around the tank. These turrets slowly move with the tank whether it’s moving or not, similar to the Auto Smasher, Auto Gunner, Auto Trapper, and Auto 5’s turrets.
The Auto 3 has 3 Auto Turrets that are automatic and fire at anything in its view range. The Bullets will prioritize tanks over Polygons or Crashers. They are twice as weak as Flank Guard’s. Turning on Auto Fire will allow you to control the turret closest to your cursor. Each turret has a 120° field of view, meaning only a maximum of 2 turrets can fire at a single enemy, and moving your cursor around the tank with Auto Fire on changes which turret you control. Turrets can also be controlled by clicking and holding. Holding Shift or Right Click will make the 1-2 closest turrets point away from the cursor. The turret’s range is slightly greater than the player’s field of vision. For both this tank and the Auto 5, Auto Spin is automatically on.
Weak Against: High RoF tanks, fast melee classes, Drone classes.
As the Auto 3
When using the Auto 3, it is advised to take caution, due to the fact that the tank is relatively weak (however the high penetration can be exploited). In 2 Teams and 4 Teams, it is highly recommended to stay close to teammates, since this tank is best used as a support role. It is also a very good tank for farming because the cannons are automatic and will shoot at any polygon within their FOV.
The Auto 3 is very weak against bullet spammers and multiple tanks at once, since it shoots a limited amount of bullets. Because of this, it is recommended to avoid tanks listed in the "Weak Against" section.
If the player is skilled enough, they can use this tank to farm at the Pentagon Nest as long as they can keep the Crashers away.
The player can use the Auto Turrets to their advantage since they have a larger FOV than the player, meaning they can detect enemies before the player can.
Against the Auto 3
When fighting the Auto 3, players should shoot into gaps between the Auto Turrets. Since it always has Auto Spin on, it cannot keep its Cannons shooting towards the player's Bullets efficiently.
High DPS tanks, like the Twin or Machine Gun branch should not have any problem killing an Auto 3. If you have good penetration and damage, you may easily out-penetrate it's weak firepower and hit them in the gaps between the turrets.
Fast ramming tanks are very strong against the Auto 3 and can easily charge through the Auto 3's fire power and collide into the Auto 3, killing it. The Auto 3's bullets, even with maximum penetration and damage cannot stop a ramming tank that easily so you may reach the Auto 3 with only little damage before ramming.
As a tank in the Overseer branch, don't hesitate if you come to fighting an Auto 3 and try to claw the Auto 3 in the gaps between it's Auto Turrets where the weak spots are and kill it without any problem.
