RoboCop: Rogue City contains seven hidden circuit boards for the Auto-9 pistol. Most are tucked into the main story, some unlock in side levels, and one secret board lies in the metallurgical factory. This guide explains how to locate a rare circuit board that remains useful until the end of the game.
RoboCop: Rogue City Guides
Where is the secret area of the metallurgical plant
When at the metallurgical plant, head toward the quarry while pursuing a lead as a police officer. Soon, enemies will contact the player and offer two extra tasks. These can be ignored in favor of the main narrative, which continues until the quest Following in the Footsteps of Officer Briggs is completed. After finishing that quest, there is time for optional activities. The secret zone lies to the east of the quarry and serves as a shortcut between locations. Access is not accidental; activating the locomotive is required.

How to get into the secret area and find the circuit board
To the east of the quarry, a ruined factory stands. Enter the basement and find a hallway filled with barrels opposite the scavenger hunt location Unclaimed Property. One of the barrels hides a technical reference that must be scanned with the RMB button.

Return to the surface and scan the surroundings along the railroad tracks. The yellow locomotive nearby is a key landmark. After examining the reference, the player can trigger a train for free. The train breaks open a metal door, revealing a new shortcut. Do not rush out of the opened room.

A marker on the map indicates a chest on the second floor, which is accessible only via the locomotive stairs. No extra equipment is necessary to open the chest. The reward includes a circuit board for Auto-9 and the achievement Great find, Murphy! (Good eyes, Murphy!).

What to improve in the Omni Board – Tier 4.2 PCB
This setup does not grant infinite ammo and incurs a 10 percent penalty to all stats, yet the boosts to accuracy and armor penetration are valuable. With solid pipe work, recoil can disappear, magazine capacity grows, and heavily armored foes become vulnerable after a few shots. Using this configuration, the player finished the game on the hardest difficulty with minimal deaths.
