Hexaswarmer is a TESTBED boss that was added on a unknown release date.
Design
The hexaswarmer has 3 sides with 3 swarm drone cannons, and 3 sides with 1 drone spawner cannon, on top reveals a Carrier turret and on each corner there is a Sounder turret there is about 6 of these Sounder Turrets.
Technical
It is a boss based on swarm drones so use the weakness of swarming tanks against it.
Spawning
Currently does not spawn. Only Testbed and Senior Testers can access it.
Strategy
You will most likely never see it in your normal game but if seen you should use these strategies. Use a bullet spamming tank to wipe out its drones. You may need a teammate with you for defeating this boss both of you can sit on each side while attacking it. Redistributor may be able to get a shot in but will be wiped out by the swarm drones, so get a teammate while fighting it if you're using Redistributor. You can also use a Kukri tank to block some of the swarm drones and make a small field where the Redistributor can shoot and eventually kill it before it can kill you. Using Hexa Builder can be useful while the Hexa Builder can press C and E to spin and shoot. This will make a fort and eventually kill it in teams.
You can use 3 or 5 Surge tanks to stun it with Shift, and it will get stunned, but this is useless if the Boss is not close to the fort.
Using Underseer branch is not a good idea, because it will shred through your Sunchips health and eventually kill you before you can kill it with no forts.
Drones can overwhelm the Hexaswarmer up close, but you will need a fort to get up close to the Hexaswarmer. This will decrease your chances of dying before you can kill it first. Now, you probably need 3 Surge tanks to stun it and make it immobile. Next, you will charge all your firepower at this boss. This will decrease its health and kill it in a few minutes depending on the Health.
