Patient Observeration Room (Dr Kellerman)

Batman: Arkham Asylum Guide - Walkthrough

Patient Observeration Room (Dr Kellerman)

As you enter the Patient Observation Area you will see that there are two bad guys in the entrance foyer you are in – while above you is a zip point that leads to a ventilation grate you cannot open just yet.  Go ahead and zip on up there anyway, and then line up the guy below on the left for a Glide Kick and finish him off, then take out his buddy to secure the area.

Now zip back up and rip that grate off the wall!  Move through the duct and kick out the grate at the other end, but do not drop down to the floor just yet.  A closer examination will reveal that there is gas below – and in Detective Mode you should see the ventilation fans – and their controls – that you need to use to clear away the gas.

The first fan is easy enough – exit the duct and move to the right where you have a clear line of fire at the first control box and Batarang the fan on.  That clears some of the gas out of the upper area, which allows you to glide across to the top of the cage on the opposite side and then work your way from cage to cage to the far end of the room, where you can target the second control box.

Some cheery encouragement is now received from the guards – and you should notice that there is a thug hanging from a rope to avoid being taken by the gas below – and fortunately for us he is suspended directly above a weakened ceiling that we need to break do get access to the final control box.  Go ahead and slice his rope with the Batarang so that he can be helpful and break the glass, then jump to the deck next to that room and hit the control box, activating the third ventilation fan. 

Dr. Kellerman is now rescued, as is Officer Aaron Cash, whose bio you get for completing this objective.  Go ahead and read the bio now, and then have a chat with him and then enter the room he just exited and grab the second Patient Interview Tape for The Riddler.  Interesting listen that.

Now retrace our steps by doing to zip-climbs back to the duct and hading back into the corridor, where a little ways down another teeth box will drop – and if you kill the three dancing teeth here as well as the ones that were in the room we just left you should get the Riddle for killing 10 Teeth!

You can see on the map that the corridor to the last doc to the east sort of splits at the head where the corridor entrance is, so make your way to there and then around toward the last target.  You will encounter three goons in the hall just before the door to the last area – so take them out as you like.
