Ace Chemicals 1

Head to the location and talk to Gordon. After the cutscene, find your way inside the facility. Enter Detective Mode once you're able and scan the area of threats. The security terminal you have to access will be highlighted in your screen. You have to make your way there but first, it will be better to take out the guards silently to make your job easier. After knocking out the guards, access the terminal.

You have to make your way to the highest vantage point in the area – the top of the Ace Chemicals building. While the batscanner is airborne, move the cursor until you feel that the controller is vibrating. Now press and hold X to scan the spot. You need to locate all five workers to complete this section.

First things first; you have to bring the Batmobile inside to help you rescue the workers. First, you need to lower the gate. Find the Security Office near the gate and clear the room of unarmed guards. Unfortunately, the worker you'll find inside is already deceased. Pull the gate release lever and take control of your Batmobile.

While controlling the Batmobile, use the power winch to pull the destroyed part of the bridge and boost it over the improvised ramp. Destroy all the tanks inside then clear the path. Now you can rescue one of the nearby hostages.

This guy is located in the room in the separate platform in the corner of the compound. Guide your Batmobile in Battle Mode across the pipes and use the power winch to take down the door. Neutralize the guards and enter the room where the hostage is located to trigger a scene.

Now after Arkham Knight's entrance and while he's talking on the phone, select the Remote Control for your Batmobile and fire the riot suppressor rounds to encapacitate the soldiers. Use your cursor to designate targets. If a soldier flies through the glass, you have to finish off the remaining soldiers by melee combat. Now free off the second hostage. Enter the Batmobile and bring the hostage back to Commissioner Gordon.
