Walkthrough - Intensive Treatment - part 2 BAA Guide
Last update: 11 May 2016
The third person you must rescue is a convict. Don't worry, because Batman will automatically stun him one he's safe on the ledge. Activate your detective mode and turn left (screenshot #2). You must use a Batarang here, aiming it at a nearby control panel. Hitting the panel with your gadget will turn on nearby fans and therefore you'll get rid of the deadly toxins left by Joker.
Proceed to the ground floor and head south. Eventually you should end up in a zone called Transfer Loop. Follow the route using green arrow seen on the floor and on the walls. This means you'll continue moving south. Watch out, because Batman is going to be attacked by two inmates along the way.
Upon your arrival in Secure Treatment Transfer you'll be forced to go up against a mini-boss. DON'T attack the mutant sent by Joker. All you have to do is to dodge its attacks by performing successful jumps. Aside from trying to ram you the beast will occassionaly throw bodies at Batman and you'll have to continue moving to stay alive.
Keep defending yourself until the beast stops and dies. You'll be rewarded with a short cut-scene and afterwards you'll be greeted by one of the guards. Wait for the guard to unlock a new passageway for you. Talk to him if you want to or return to the Transfer Loop zone right away. This time you'll want to head north.
Eventually you'll have to return to a small junction where you've been attacked by the inmates the last time you were here. Head west. New inmates occupy the western section of this area and it would be a good idea to surprise them by using Batarangs. You can also attack them without any delays if you feel confident about your win. Once they're pacified go north and return to Holding Cells.
Listen to a new radio conversation with Oracle along the way and once it's ended enter a large room located to your left. Turn on your detective mode and scan the area in the search for a whisky bottle. Press and hold the scan key while targeting the fluid. Doing this will isolate a forensic trail, allowing you to continue your investigation and the search for Frank Boles.
Exit the room and proceed south. This means you'll be returning to Transfer Loop. It would be a good idea to use detective mode from now on, because you'll encounter a lot of clues on where to go next. Choose the corridor leading south and once you've reached a new door proceed to an area called Security Transit. Approach a guard here and witness a new cut-scene.
Get ready for a rather challenging section of the game. Your objective will be to reach the top floor of this elevator shaft. Start off by using your hook twice to grapple up to higher platforms. Once you're standing on the higher platform run forward and Batman will automatically jump in order to grab a nearby ledge.
Notice that Batman can't climb up so as a result you must move to your right. Don't worry, because the main character won't lose grip at any point of the game. Climb up when you have the chance, turn left and move forward. Kick the grating to leave the shaft and use your hook once again in order to reach a higher platform.
There's a large hole in front of you and you'll obviously have to jump over it which shouldn't be a problem. Once you're on the other side press the crouch key and head forward, ignoring a ventilation shaft seen along the way. Climb up to a higher platform and grab the ledge. This time you'll be moving to your left.
Keep heading in the direction mentioned above until you'll be allowed to climb up to a new platform. Move forward and use your hook several times more to continue your approach to the top floor. Don't worry if you can't locate your destination right away, because in some cases (screenshot #2) you'll travel a long way.
