Pendulum

is a tier 5 tank that upgrades from Frigate and Clockwork at level 60.

Design
It is a Clockwork with bulkier swarms. They look like a Clockwork but the swarm Spawners are larger.

Technical
Like all Clockworks, the bee Spawners are always firing, and the ones on the back fire when the user clicks, presses space or toggles autofire.
