Arkham Knight HQ North
Riddler Trophy 1: On the top level, sitting on a tabletop.
Riddler Trophy 2: Remote Hacking Device, Remote Electrical Device - Use the Remote Hacking Device to open the door. Once inside, use the Remote Electrical Charge to start the ball slowly rolling. Then use it on the Question Mark to move the green parts of the maze. Once the ball is past each green part, shoot it again. Collect trophy.
Riddler Trophy 3: Batarang, Batclaw - Use the Batarang on the Question Mark. This will make crosses appear on all but one monitor, which will have a Question Mark. A white light will start to circle the monitors, and you will need to use a Batarang on the central Question Mark so that the light stops on the monitor Question Mark. Do this three times, and then use the Batclaw to grab the trophy.
Riddler Trophy 4: Batmobile, Power Winch, Batclaw - Use the Power Winch to lower the Batmobile onto the pressure pad. This will start a ball rolling down the slopes opposite you. As the ball approaches each red circle, shoot the Question Mark above it to open the hatch so the ball can keep rolling. When the ball reaches the bottom, it will start again, this time with two balls. Shoot each Question Mark that has a ball close, and when both balls reach the bottom, it will finish. If you fail, the ball will start again from the top. When completed, glide down and use the Batclaw to grab the trophy.
Riddler Trophy 5: Remote Hacking Device, Batarang - Each of the buttons will start the cog rotating. The Question Mark changes the direction of rotation. Use the Batarang on the Question Mark to change the direction of rotation. For each cog, there is a guard barrier around one side of it to stop the ball from falling. Use the Remote Hacking Device to start the second one moving and stop it when the gap for the ball is at the top. Then use the Remote Hacking Device on the top one to bring the ball down. Then use the Batarang to change direction, as the barrier is on the other side. Use the bottom button until the ball catching hole is at the top and stop it. Start the middle one to transfer the ball down. Then change rotation, and start the bottom one moving and get your trophy.
Riddler Trophy 6: Remote Electrical Charge - Use the Remote Electrical Charge on the generator to spin the cog. Turn it in each direction necessary to get the ball over the next obstacle. Three directions are needed. Get trophy.
Riddler Trophy 7: Remote Electrical Charge, Explosive Gel - Get on top of the elevator and use the Remote Electrical Charge on the generator on the elevator roof to raise up. Use the Explosive Gel on the breakable wall and boom. Walk in and get the trophy.
Riddler Trophy 8: Remote Hacking Device, Batclaw - Access Via Elevator Shaft From Level 5. Use the Remote Hacking Device to open the door. Then stand in the elevator and look down underneath where you walked in. Use the Remote Hacking Device on the button to open the door. Use the Batclaw to grab the trophy.
Riddler Trophy 9: Remote Hacking Device, Remote Batarang - Use the Remote Hacking Device to disable the turret. Then stand on the pressure pad. This will open a panel on the wall to the right. Then use the Remote Batarang to follow the path around the corner, to the end and turn right to hit the Question Mark. This will open the panel straight ahead, where there is an electric charge. Yep, got to do it again. Throw the Remote Batarang down this path to give it an electrical charge, and around the corner to the left. At the end is another turn to the left and a path that will lead to the room with the turret. On the far wall up ahead is an electrical box. Hit this with the charged Batarang and the gate will open. Walk in and pick up the trophy. Easy.
Riddler Trophy 10: Sitting behind a mannequin. Pick it up
Riddler Trophy 11: Batclaw - On top of the Lounge Bar sign. Use the Batclaw to grab it.
Riddler Trophy 12: Remote Electrical Charge - From level 3, go to the southern section with all the pretty lights. Grapple up onto the elevator on the right. Enter the elevator and use the Remote Electrical Charge to take it down as far as it will go. Then exit the elevator and send it back up a level. Enter the shaft and pick up the trophy.

Riddler Trophy 14: Remote Hacking Device, Remote Electrical Charge, Batclaw - Use the Remote Hacking Device to open the door. Inside, use the Remote Electrical Charge on the generator to spawn two slow moving balls that follow the path. The Question Marks change the position of the green bits of path.
