The antagonist of the main character abused his official position: he installed security turrets on the chassis of repair robots. For power supply, he adapted nuclear units from a generator at a local power plant. The result is combat vehicles that tirelessly patrol the area. To launch the portal, the main character must return these blocks to their place. If you sneak up unnoticed, the block can be pulled out using the pickpocket mechanic. But it’s still easier to kill this robot.
