Powerhouse

The Powerhouse is a tier 5 tank that upgrades from Overdrive.

Design
The Powerhouse looks like the overdrive, but the grey topper is an octogon instead.

Technical
The Powerhouse is like overdrive, but instead of small auto turrets, there are small Director auto turrets that spawn director drones controlled by AI.

Trivia
The Powerhouse's drones' drones circle around the Powerhouse itself, not the drone that spawned them
