AT4 BW

The AT4_BTW is a testbed boss with the EMP effect.

Design
The AT4_BTW is a triangular boss with 3 white triangles in the center, aligned in a way to represent a triangle, and a hexagon behind it. It also has a EMP Crasher Spawner.

Technical
AT4_BTW has decent firepower and DPS. It has an EMP effect from the drones.

Spawning
Spawns in boss rush, and rarely in other modes.

Countering
At first, it may look easy, but it will take more than that. Use at least 3 Hexa Builders to fend off those crashers. You can use bullet spammers too. Optic branch optional, though. At least have 1 Apidae on your side. That way, it will die faster. You can also use Redistributor, too. As you proceed to damage the boss, you are pretty much ready. Expect your team dying a few time, unless the boss gets killed by another team. Try avoiding the EMP with a Surge to stun the bullets or use a Tri-Angle branch. Use destroyer branch if you want to destroy the remaining chasing crashers before you are screwed.
