Wayne Tower is located in the south-eastern part of the island. Just like before, use your ability to glide to avoid the tanks parked in the streets. When you reach your destination, use the grapnel to reach the top floor of the building. Talk to Lucius Fox and use the main computer to analyze the encryption protocols.
Lastly, you need to decide what upgrade to install in the Batmobile.
- Drone Hacker upgrade - CPU Virus - enemy machines can be hacked to fight on your side.
- Secondary weapon upgrade - Weapon Generator MK III Upgrade - allows the weapon to be overloaded, which will increase its firepower.
Note - the upgrade that you choose will not be installed right away. This will happen a bit later and you can't miss this moment.
