Fanon:Barge of the Polygons (GellyPop)

The Barge of the Polygons, or simply Barge, is an AI-controlled boss concept for Diep.io. It uses explosive drones as weapons, along with barrels and auto turret.

Design
The Barge features a green Pentagon body, with one flat side of it acting as its back. Five barrels formed like the Streamliner's weapon are placed on the front. Three drone spawners are placed on the back sides of the Barge, one for each side. Lastly, a quad auto turret is placed on top of its body.

Technical
Although it spawns drones and shoots bullets, the Barge acts more like a ramming Boss, like the Fallen Booster.

The Barge has an incredible amount of 4,580 health, much higher than the Fallen Booster. However, it has weak healing factor. The Barge only targets players level 15 and higher, unless provoked.

The spawners spawn explosive drones. These drones are like the Hwacha's drones, making very small explosions when destroyed. Each spawner spawns 8 drones, making the total of 24 drones. They also does much recoil when spawning drones. Take note that the explosive drones doesn't disappear by themselves, and that every drone may chase different tanks, not just the Barge's target. Also, the Streamliner-like barrels on front of it fires non-stop, unless there are no nearby players on range. The barrels do no recoil. The quad auto turret spins faster than a tank with auto-spin enabled, and doesn't directly aim at the players. However, it has farther detection range, about as large as the Ranger's FoV. All bullets does minimal damage, although constant receiving of them is deadly.

Strategy
The Barge is much like the strengthened version of Fallen Booster, but slower. Try to escape away from it. Avoid all of it bullets. Shoot down the explosive drones.
 * Strong Against: Melee tanks, tanks with low Reload, drone tanks (when being chased)
 * Weak Against: High DPS tanks with high Bullet Penetration

While being chased down, try to move out to avoid the bullets. Also, avoid the bullets shot by the quad auto turret. Lastly, try to destroy the explosive drones as they can eliminate you with ease.

When not being chased, use the chance to attack the Barge. Avoiding the auto turret's stray bullets is not much a hard thing. If you can, try to catch up in the front side of the Barge, so that the explosive drones won't cover much of your bullets. Be careful however when the Barge had eliminated its target, as it might suddenly target you.

When playing team game modes, it is best to team up with other players of your team. Having at least one Trapper branch and two other high DPS tanks should be enough to take down the Barge.

Trivia
