Pendulum

 is a Tier 5 Tank that upgrades from Clockwork and Frigate 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. The bee spawners are always facing the same direction no matter which way your tank faces.

Trivia

 * This tank somewhat resembles a game controller, with the Frigate guns as grips and the Clockwork spinners as triggers.
