Medical Facility--Part 2

Locate and Rescue the Three Doctors

Doctor Young

The three doctors locations are all marked on your map. You can meet-up with them in any order, though for the purpose of the walkthrough, we suggest heading for Dr. Young first. To get started, drop to the bottom floor and head right, through the door. Now follow the yellow line on the ground to the X-Ray room, where you'll hear some commotion inside the central room. In order to save Dr. Young, you'll have to plant two gel charges and detonate them at the same time. Use Detective mode to find the first weak wall on the front side, then run around to the back to find the second inside a small alcove. With both gels planted, detonate them to free the Doctor--just don't take too long, otherwise they'll kill Dr. Young before you can save her.

Doctor Chen

Exit the room where you freed Young and follow the hall to a red stripe on the floor, which leads to Dr. Chen. Inside, you'll have to battle some dudes who'll drop from the floor above. With the room cleared, interact with Dr. Chen to free him.

Doctor Kellerman

With Chen freed, head back through the hall and follow the blue painted stripe to locate the final Doctor. After going through a door, you'll spot the Doctor trapped within a small room, being guarded by two inmates. Kill them, then grapple onto the high pipe, left of the window, where you'll find a ventilation shaft you can bust into. Follow it into a large, poison-filled room.

You'll have to ventilate the area by activating a couple of fans, similar to how you did before. For the first one, follow the walkway to the right and use Detective mode to find a control panel a few meters below the vent you emerged from--toss a Batarang at it to activate it, clearing the poisonous air from the upper levels. Now head to the opposite side of the walkway and glide from it to a platform ahead, then jump across a couple more. From the last platform, turn around to face the one you just leapt from to spot another control panel just below--toss a Batarang at it too to clear some more of the poisonous air.

With the second fan activated, glide to the low platform ahead (the one with the ladder). Now if you haven't already, use a Batarang on the hanging inmate above to cause him to crash through the roof of the room below, allowing you to toss another Batarang at the final control panel inside. This will clear the room of poison once and for all, freeing Doctor Kellerman. Before leaving, check the office the Doctor escaped from for an Interview Tape.

Return to the Doctors in the Sanatorium and Pick Up Gordon's Tobacco Trail

With the final Doctor freed, you'll have to return to the ones back in the Sanatorium. To get there, grapple back up to vent you used to enter the room, then follow the red and blue painted stripes to the door on the right. After the cutscene, Batman will automatically grapple to a gargoyle in preparation of three approaching enemies. Simply wait for them to walk by, then drop down and enter the lift they just exited from. However, if you really want to take them down, simply use the glide-kick and grappling to a gargoyle-to-a-gargoyle strategy that we've outlined before.

After riding the elevator and watching the cutscene, detonate some explosive gel on the weak wall, left of the window, to reveal a hidden tunnel. Follow it to spot Commissioner Gordon being dragged away--chase after him by busting into the ventilation shaft on the left and approaching his slain body after exiting.
