On this page of the Gotham Knights guide, you will learn how to complete Chapter 7 - The League of Shadows, and solve the puzzles with the serum and frequencies on the tower.
Friends in Need
In the first mission, you have to save at least two people you met earlier as part of new operations in the city. The order is optional, but from now on, other activities in the city are locked. There, you will fight The League of Shadows. After completing the tasks, return to the hideout.
Talia al Ghul
The second mission will start after visiting the hideout. Visit the city again and head to the northeastern part of it - Arkham Asylum. Get ready to battle the numerous League of Shadows fighters.
Puzzle with vials
Get into Arkham Asylum. This is where you will discover another puzzle: you need to match Serum V24.07 and Genetic Marker M. Now go through the side corridor to get to the basements. After returning to the top, you will face a large group of the League of Shadows enemies.
Puzzle with amplifiers and frequencies
Reach the tower. Align the frequencies for the devices. To solve this puzzle, you have to align the amplifiers in the correct order. Look at the main screen and the shape of the first wave segment. Find the small screen that corresponds to this shape. Now check to which screen the wire connects and set the correct frequency on the corresponding amplifier. Then the color will change to green on both the main monitor and amplifier. If you make mistake, you can reset the settings at the terminal and try again.
Finally, you will face a new mini-boss: Man-Bat . The key to winning is quick counterattacks after dodging and avoiding toxic attacks (yellow mist around the claws). He can also attack from a distance using sound.
