The King

The King is a boss that was added secretly into the game, however, it was certainly added after December 6, 2018. Currently, it is on TESTBED bosses branch.

Design
The King has an irregular oblong light blue heptagonal base with a smooth wedge in front and slanted back. At the back, it has a slightly misaligned Machine Gun, and on top of its base, The King has three Planer auto-turrets, each after another. On its sides, The King has six Annihilator turrets.

Technical
The King has normal health and speed, and very strong bullets. Its planer turrets have medium reload, and shoot fast bullets with high damage and penetration. Its side turrets shoot bullets of the same strength, but at a faster rate. Bullets of the machine gun are weaker but have more spread and the turret has a fast RoF.

Spawning
Currently does not spawn.

Countering
The King has high firepower and medium speed and has excellent offensive capabilities. Its bullets are hard to penetrate, have high speed and damage. If distracted by another player, it still has good defensive capabilities thanks to the side turrets, which are even stronger than auto-Planer turrets. It's using its back turret to propel itself forward, so very slow tanks will not work. Due to its strange shape, it may be able to go through an obstacle like a rock. As such, it is advised to attack it with a coordinated team.

Have at least one player distracting The King, ideally a fast tank with high penetration. The King should lock on that player, while the player should keep a safe distance and penetrate its bullets. In the meanwhile, other players should be attacking the boss from the back, shooting it between its back and sides. One auto-turret will lock on you, so make sure to have a high movement speed and penetration.

Trivia
