“No stone unturned‘ is an early game achievement/trophy in RoboCop: Rogue City is what is asked of players find a secret area in the arcade. It’s definitely worth doing this, because you’ll find a hidden power-up (a OCP training disc) for your efforts. Here you will find the secret area in the arcade RoboCop: Rogue City.
Where to find the secret area in the arcade in RoboCop: Rogue City
Since RoboCop: Rogue City is chapter based and some areas are locked out for you after you complete certain story missions. Certain trophies and achievements can also be easily missed. Happy, Rogue City autosaves a lot, including at the beginning of chapters, so you can reload a save often to catch anything you missed – including the OCP training disc in the secret area in the arcade.
To find the secret area of the arcade, you must first go to the basement. That’s simple enough; Simply find the drugged child in the arcade bathroom and scan him, which will automatically give you a warrant to search the premises. Down in the basement you will encounter a gang of Torch Heads. As you head to the arcade owner’s office and kill everything that moves, you’ll see the secret area just to the left of a neon Nuke sign. It is closed by an iron gate.

To unlock the gate of the arcade’s secret area, you must visit the arcade owner’s office. He is being held hostage by a group of Torch Heads, and whether you decide to rescue him or not is up to you (and does not affect your ability to access the secret area).
Once the office is clear of threats, you’ll find a secret button on the right side of the owner’s desk. Scan it with your RoboCop vision to bring up the ‘press the button’ prompt.

Return to the unlocked secret area and claim your prize: a bunch of stolen goods (which will give you enough ‘crime evidence’ to allow you to complete the levels of the level Side mission of police work) and one OCP training disc that gives you a skill point.
