EK-X

The EK- series of bosses are powerful bosses based on the Egg. They come from the death of an Egg Sanctuary. Usually the series starts off as EK-1, though it is possible to start as an EK-2. EK-3, -4, and -5 are considered server crashers, and EK-6 is known to exist but has never appeared in-game outside of developer events.

Design
The EK- series uses a white smasher base. EK- bosses are based on the Egg, much like the TK- series is based on the triangle.

Each smasher side has a number of turrets, whose firepower increases greatly with each evolution. There is a very strong swivel turret, which increases in power and/or number with each evolution.

Strategy
Using very high bullet spam tanks or teaming up against an EK-1 or EK-2 is easy to accomplish and the boss will die quickly. When fighting the EK-1, it is possible to circle around the boss like an AI, making the boss' bullets fire slightly behind you. With EK-2 and higher tiers, this is impossible without teammates as swarm drones and extremely powerful minions are spawned.

EK-3 has been observed only a few times outside of developer events. EK-4 and EK-5 have only ever been seen in developer events. EK-6 has only been observed being used by game developers in a private server. These bosses are so powerful that they cause extreme lag and can crash the server.
