Hive

The  is a Testbed Misc tank.

Design
The tank looks like one of Swarmer's fired hives.

Technical
You cannot aim the since it inherits the rotation-based-on-movement-speed mechanic of Swarmer hives. Its barrels are also uncontrollable, constantly spawning bees that loop back around to you and cluster around your position.

Strangely, the cannot deal or receive any damage, similar to the Disappointment.
