On = Drones will move towards the player’s cursor.
Off = Drones will attack any entities which are “hostile” (Polygons included) automatically if no buttons are pressed. If there is nothing to attack, they will circle aimlessly around the player unless there is somthing to attack.
Shift/Mouse (Right/Left buttons): Holding the left click, or space, on the mouse will make the Drones move to the player’s cursor. Holding 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.
Strong Against: Slow tanks, low DPS tanks, Sniper branch (when up close), Tri-Angle class (if your Drones focus on one).
Players can earn EXP by staying at the very corner of the map and sending out their Drones via right click/Shift. However, while doing this, players should keep in mind that an Overseer without its Drones is defenseless. This would not be an issue in 2 Teams or 4 Teams, as players can camp in the home base. It is a useful tank for playing 2/4 Teams as the Overseer can protect teammates. When attacking, players should try going for distracted or low Reload tanks. Tanks with a higher rate of fire can defeat the Drones while running away. Expert players can send their Drones exactly to the Pentagon Nest.
Players in a tight spot with lots of Bullet fire can try rallying their Drones to protect them. Having its Drones far away from itself makes the Overseer very vulnerable since the Drones are its only weapon.
Surprisingly, it’s actually quite possible to fight an Overlord, an upgraded version of an Overseer, and win with the proper upgrades, though this can be dangerous because the Overlord has double the Reload, as well as more upgrade points.
It is also possible for Overseers to defend themselves from a Tri-Angle and its branches using a certain maneuver 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 Drone classes, but if done correctly it can save the player's life from a Tri-Angle or its branches. To perform, the player must first be attacked by a Tri-Angle, then as it races towards the player, the Overseer should call your Drones to hover over it while charging towards the Tri-Angle, shortening the distance between the two tanks. If all goes well, the player's Drones should be neatly sitting on top of him, with the aggressor circling, trying to find an open area to attack. This is the player's chance to slowly inch away to base, while if needed sending the Drones out slightly to keep the aggressor at bay. If the player does this correctly and survived with even a sliver of health, they have managed to pull off one of the hardest maneuvers in all of Diep.io.
Against the Overseer
Players looking to counter the Overseer can use Classes like the Tri-Angle. They can easily maneuver 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.
Skilled Smashers also have a great chance of victory, however, this only happens if they catch an Overseer at the right time (with its Drones deployed).
