The tower has been erected on a small isle neighboring the Amusement Mile. Still, you can reach it with no problems at all. Explore the lower part of the isle to find the tunnel shown in the above screenshot. Use the glue grenade here to create a floating platform. Jump onto it and start to move, using the claw on the interactive anchor points.
Jump up to reach a small ledge, turn right, open the door and grab onto the ledge above, using the hook. Again, you need to use the glue grenades here, this tie to seal two pipes and stop hot steam from leaking.
Enter the room with a small group of bandits in, start fighting and try preventing your enemies from using guns and knives, to the extent it is possible. After the fights, examine the ceiling shown in the screenshot and cause it to collapse, using the claw on the interactive anchor point.
Note that you have unlocked access to the vertical shaft. Select the grapple from the inventory and extend the rope. After you do that, use the hook to reach the rope. Go ahead and keep cautious in the corridor with another group of criminals, because one of them is packing a gun. Also, avoid coming into contact with the discharges, although you can push the enemies into them to inflict additional damage to them.
Continue along your path to the top level and open the reinforced door. Use the Cryptographic sequencer on the control panel, which will start the hacking minigame and let determine the correct password (the screenshot).
