Controlled Access

Batman: Arkham Asylum Guide - Walkthrough

Controlled Access

You get the Riddle: “What has four walls, two sides, and an ex-DA?” as you enter, and you should see an enemy ahead and above you as well.  As you enter this area, go into the first cell on the right and scan the poster on the wall – it says Vote For on it – to solve the Riddle.  Now run to the end of the block and you will see a forcefield with its control wire extending up top the ceiling – and a grate nearby where it goes in.  Grapple the grate and pull it down, and kill the Lunatic who falls down the open grate hole.  Now zip up there.

Hack the control box up here and then turn around and grab the fourth Patient Interview tape for Mr. Zsasz, then run over and take down the other Lunatic.  BTW you should have picked up another Bio  this one for Two Face – at some point. 

Along the right wall on the second floor are some weakened walls – go ahead and blow these now.  The cell on the left has a Riddler Trophy in it so grab that now, and then pop back up and go down to the first floor, that last area on the left where the forcefield was that belonged to the control box we hacked.  Inside here is the door to Extreme Incarceration.
