Overseer

The Overseer is a Tier 3 tank that can be selected starting at Level 30. Once upgrading to an Overseer, you will spawn Drones. The Overseer has a Drone capacity of 8. The Overseer can be upgraded to Overlord, Necromancer, Manager, Overtrapper, or Battleship.

Design
The Overseer has a circular base, with two trapezoidal Barrels on opposite sides of the tank facing outwards.

Drones
The Overseer's two Trapezoidal Barrels will continuously spawn Drones which will move to the player's command.
 * Auto-Fire (Press 'E')
 * On = Drones will move to the player's cursor.
 * Off = Drones will act on their own, and kill any entities which are "hostile" automatically, if no buttons are pressed.
 * Mouse (Right/Left buttons): Holding the left click, or space, on the mouse will make the Drones move to the player's cursor. Holding the right click, or shift, causes them to move away from the cursor, holding it will move the Drones in the opposite direction of the mouse's position as to where the cursor is. For example, holding right click north of the Overseer will move the Drones south.Ogrelord.png

As the Overseer
Staying at the very corner of the map and sending out your Drones via alt fire can reward points from far away. However, while doing this take in mind that an Overseer without its Drones is defenceless. This would not be an issue in Team Deathmatch, as you can camp in the home base. It is a useful tank for playing Team Deathmatch as you can protect teammates. When attacking, players should try going for tanks with a lower rate of fire or are distracted. Tanks with a higher rate of fire can defeat the Drones while running away.

Players in a tight spot with lots of Bullet fire can try having Drones rally to protect them. Having Drones far/away from the Overseer makes it defenceless.

It's actually possible to fight an Overlord, an upgraded version of an Overseer, and win with the proper upgrades, however this can be dangerous because the Overlord has double the Drone production speed and faster Drone Speed.

It's also possible to defend yourself from a Tri-Angle and its branches using a certain manoeuvre that can only work in game modes with Bases. It's very risky and can usually only be done with players with a lot of experience in summoning Classes, but if done correctly it can save your life if you are being rammed by a Tri-Angle or it's branches. To preform, first, be attacked by a Tri-Angle, then as it is going towards you call your Drones to hover over you while you race towards them, shortening the distance between you and your Drones. If all goes accordingly your Drones should be neatly sitting on top of you, and your aggressor circling you, trying to find an open area to attack. This is your chance to slowly inch away to your base, while if needed sending your Drones out slightly to keep your aggressor at bay. If you have done this correctly, and survived all of this even with a sliver of health, consider yourself either extremely lucky or skilled because you managed to pull of one of the hardest manoeuvres in all of Diep.io. Good job.

Against the Overseer
Players looking to counter the Overseer can use Classes like the Tri-Angle. They can easily manoeuvre around Drones and ram the Overseer. Players should ram the Overseer before it can get its Drones close enough to protect it.

Tanks with massive Bullet Penetration such as the Destroyer can kill 4 maxed out Drones (Drones with max Drone Speed, Health, and Damage) of the Overseer's Drones with one shot, and then move in to kill it.

The best build against an Overseer-branch glass tank (as more than half of them are) would be a 00077775 predator, it has a larger default view than a Drone tank and it can move it to aim more accurately. The damage on even the tiny bullet deals half health to a glass Overlord.

Trivia

 * Overseer is the first tank ever to use a different Bullet control system by using Drones that follow your cursor instead.
 * As of August 28th, the Overseer, the Tank, and the Trapper has the highest number of upgrades, being 5.
