Grindmind

The  is a Testbed Overdone tank.

Design
The tank looks like the old version Geargrinder with the Carrier spawners on the back, but with the dark outline of Hivemind.

Technical
The tank is basically a Hivemind variant of Geargrinder, allowing it to spawn clones of itself. It is unknown how many clones it could make but it is presumed to be a lot since it was locked in Overdone.
