Pursue Black Mask | Main storyline Batman: AO Guide

watch out for the armored opponent

Right after you get tot the chamber where the most recent cutscene took place, you will start a fight with another group of gangsters sent by the Black Mask. While fighting, you should , first of all, watch out for the attacks of the armored enemy. This bandit is best if left for the end. In the already learned way, first stun him with your cape. After you have dealt with your enemies, take the door to the side corridor [Security Corridor]. Reach the end of that corridor and note that Batman found a Memory Card on a destroyed drone.

Keep using the hook on the successive ledges

Start climbing. You need to reach the Watch Tower located at the very top. Along your way, keep using ladders and stairs, and also occasionally help yourself with the hook to reach the less accessible ledges. After you get to the rooftop, you will watch a cutscene and you will have to fight the game's first boss, which is the Killer Croc.
