Constellation

Constellation is a special boss that was added with the release of the game. Its size was changed multiple times. On its death, it splits into 1 Constellation Core and 4 Constellation Shards. After Constellation Core and Constellation Shards are killed, the boss is considered defeated and new bosses can spawn.

Design
The base of the Constellation is the gray square, with the yellow rhombus around it. On each side of the Constellation base, a shard is located. Shards have a beige, square base with an auto-turret on top. Summed up it seems to be a big Supersplitter Square with turrets stuck onto it.

Technical
Although the only ammunition of the Constellation are automatic bullets, they are very powerful. They have fast speed, damage, and penetration. They also have a high spread, considering Constellation slowly spins and turrets shoot from 4 sides. Minigunner cannot penetrate bullets when moving towards Constellation but can penetrate bullets when moving away. Minions can hold off the bullets for some time.

Constellation has a strange hitbox: only the gray square can be hit by bullets.

Countering
Constellation is an incredibly powerful boss, as its bullets are excellent as offensive and defensive weapons. You will have troubles when attempting to penetrate the bullets and exactly hit the hitbox, while Constellation can steadily deal damage to you. All Constellation's bullets drastically decrease your Shield so you may have a problem regenerating while actively fighting.

The above means, it will be very hard to kill it in solo. It is nearly impossible to outgun it, and very hard to keep minions near you so it cannot damage you. Constellation has a lot of health, so don't be tricked by its small health bar. It has as much health as an average boss. However, its vulnerability is that bullets can only be focused on one player at a time.

Having said that, have a player that distracts Constellation. Whether that's Builder AI or dodging booster, Constellation will focus on it. Still, be vary. You may not be able to kill Constellation before it kills the distracting player, then it will immediately focus on you. If it has less than 15% of health, keep firing. Otherwise, retreat.

As a minion tank, keep minions between the boss either way. It takes great skill to keep part of minions firing at the boss, and the other defending you. Anyway, try to take cover so that you may regroup.

When in solo try using a high penetration tank that can input enough damage to the boss as well as defending you form taking too much damage.

Using a tank like Torrent or Bent Hybrid while circling around the boss can deal enough damage to kill it. When it dies get as far away; you will not be able to kill all the shards fast enough.

With Heaven Beam, simply retreat while dumping airstrikes in front of Constellation's path. Place the bullets right to get the max damage out of them when they detonate. When Constellation is defeated, throw down LOTS of bullets to kill one or two of the shards.
 * -|Constellation Core=

Design
The base of the Constellation Core is a yellow square, with a necromancer spawner attached to the turret. The turret has a white fill and a gray stroke. On each side of the base a stationary triplet turret, partially covered in trapezoids is located.

Technical
Constellation Core is the weakest shard. It always spins and shoots no matter what, and only its projectiles that lock on the player are necromancer drones.

Bullets and drones are weak and can be easily penetrated.

Spawning

Countering
Constellation Core is very weak since it does not lock on players. It slowly spawns weak necromancer drones, but they have too little health to represent a serious threat. Bullets can be dodged since you can move along with Constellation's Core auto-spin.

Overall, Constellation Shards are far stronger, and it is advised to get rid of them first. If you managed to kill Constellation Shards, killing Constellation Core will not be a problem, but it still has decent health. Bullet spammers are recommended, although minions and drones can also deal with it somewhat efficiently. Again, Heaven Beam is highly recommended.
 * -|Constellation Shard=

Design
The base of the Constellation Shard is a beige irregular convex pentagon, with an auto-turret on top. In front of it, a Pelleter turret is located.

Technical
Although Constellation Shard is a miniboss, it is still very powerful. Its bullet speed ends up creating stacked bullets, which do as much damage as Constellation's. The only advantage is that you can outgun it before it kills you.

Countering
Constellation Shard should not be underestimated: it can stack bullets and deals heavy damage to the defenseless player. Although, they come in numbers. You still have to be careful.

When countering Constellation Shard, try to focus all your firepower on it. In this stage, you can outgun it. If there are multiple shards attacking you, try to dodge by moving left-right, also. As a drone/minion tank, always keep your drones/minions close. If there are multiple shards, keep them even closer.

As a minion tank, just shoot at them while keeping your minions very close. If you are a drone tank, it is more tricky. You will have to retreat while constantly charging one shard with multiple drones while keeping all other drones near you to protect you from incoming fire.

Ideally, you should distract one shard away, then kill it. Then distract two shards, and also kill them. After that lure last shard away from Constellation Core and also eliminate it. This way you can quickly eliminate all shards with decreased danger.

As Heaven Beam, you will want to fight only one of the shards at any time; that's how fast they are. Invest your extra 6 points in move speed in order to be able to outrun the Shards. Keep dumping bullets to kill each shard. When done with all four, turn on the Core.
