Walkthrough - Penitentiary - part 2 BAA Guide
Last update: 11 May 2016
You'll have to act quickly from now on, because otherwise the guards are going to be killed. Once you've hacked into the first panel move to the right quickly and find the second control panel (screenshot #1). Use the sequencer again and after that choose the Batarang from your inventory. You must now cut two ropes to free the hostages. Once you've rescued the second of the guards you'll be informed that you have only 30 seconds left.
Turn around quickly and return to the door you've used to enter this room. The doors are locked, however you'll want to hack into a nearby control panel. Assuming you didn't make any mistakes you should have more than 10 seconds left on the clock after you've successfully disabled the terminal. You'll soon end up in a safe place where you'll be allowed to talk to Louie Green.
Turn around once the conversation has ended and return to the Main Cell Block. Be careful, because you'll encounter one more insane person along the way. Proceed to the eastern cell block and keep heading forward. You'll soon receive info from Harley, informing you that a new passageway is now open. Go straight ahead to end up in Controlled Access.
Continue moving forward. Once you've reached the opposite end of the corridor use a Batclaw on a nearby grating. Watch out, because your action will result in one of the crazy inmates landing near your position. Neutralize him quickly and then use your hook to find your way to an upper floor.
You should end up standing inside a control station and obviously you'll have to use your sequencer again. Interact with a nearby control panel and once it's been destroyed a nearby door is going to be opened. You can now spend some time visiting nearby balconies in the search for a second inmate or you can proceed to the ground level right away and enter Extreme Incarceration.
Get ready for a challenging battle. Don't be fooled by the fact that you'll be going only against standard thugs, because it'll be easy to die. Make a few steps forward and listen to what Harley Quinn has to say. Once the monologue has ended the first group of enemies will arrive.
The biggest difficulty here will be the electricity, because certain sections of the room will be electrified from time to time. As a result not only you'll have to keep attacking enemy units, but you'll also have to prevent Batman from being fried. Whenever you notice floor panels charging up go to a different section of the room. There's a central platform and two balconies, so you'll have to plenty of space to choose from.
Three areas mentioned above will become electrified in a certain sequence, so you should memorize the pattern to know where to go next. Defeating the first wave of inmates is going to be easy, however you'll soon start encountering enemies equipped with melee weapons and stun guns. Don't forget to perform jumps and to use your cape to achieve victories. You have to keep defending yourself until all the inmates have been eliminated. This will trigger a new cut-scene, showing the capture of Harley Quinn.
There's nothing else for you to do here (aside from collecting secrets, of course :-)), so you can return to Controlled Access without any other delays. From there travel to the Main Cell Block. Be careful, because you'll encounter an insane patient in the dark corridor. Defeat him and proceed to Cells Access.
Three other inmates have arrived in the meantime and there's all of the insane kind. One of the inmates can be found in the bathroom and the remaining two will attack you on your way to the exit (screens 1 and 2 respectively). Neutralize them all and use the main door to head back to Arkham West.
