Added Rogue Clockwork to the list (!) encountered in Penelope Yin's missions (not surprising given Primal Penelope's nature!). Similar to standard clockwork in all respects except (for example):
Glitched Sweeper
Rogue Clockwork - Minion
Sweepers are often seen patrolling the street cleaning up litter and debris to make Praetoria a more beautiful place to live. They have an innocuous appearance, however if threatened they are more than capable of defending themselves. These Clockwork appear to be malfunctioning.
Edit: here's an example of Anti-Matter's Clockwork, it's an enemy NPC in one of Penelope's missions
Vacuum Bot
Anti-Matter's Clockwork - Minion
Sweepers are often seen patrolling the street cleaning up litter and debris to make Praetoria a more beautiful place to live. They have an innocuous appearance, however if threatened they are more than capable of defending themselves.
Scrub Bot
Anti-Matter's Clockwork - Minion
Cleaners are designed for simple labor intensive tasks like cleaning, welding, and repairing other Clockwork. They have an innocuous appearance, however if threatened they are more than capable of defending themselves.
