The Overseer is a Tier 3 tank in Diep.IO. It upgrades from the Sniper at level 30 and upgrades to the Overlord, Necromancer, Manager, Overtrapper, Battleship and Factory at level 45. Upon upgrading, the Sniper barrel is replaced with Drone Spawners at opposite end of the rank. They will automatically spawn Drones and will continue to do so until the capacity of 8 drones is met.
