Investigate the steel mill - drug lab | Main storyline Batman: AO Guide
Last update: 11 May 2016
Your new objective is to find the Black Mask, who is being kept in the side room. Of course, the Joker's people will be obstructing you from performing this task. Just like before, try to avoid being detected at all costs. While executing the plan and planning on your actions, (inverted takedowns, grapple, gliding) you will find the statues, under the ceiling, very helpful.
Just like in the case of your visit to the bank, in your attempts to locate and surprise the enemy, you will be effectively obstructed by the enemy with the disruptor. Just like earlier, I recommend that you find him soon after this scene starts (the antenna on his back) and eliminate him.
You can clear the lab in various ways but, it is worth pointing out here that you can hide in the venting shafts and blow up some of the elements of the surroundings, using the explosive gel. Apart from that, I recommend that you use the grapple on the propane tanks and send it towards the enemies. After you have secured the entire area, go towards the South-Western door to reach Black Mask's Office and initiate a series of important cutscenes of the meetings with Black Mask and Copperhead.
