I didn't make it!
When i enter the turret gun room on the monorail level, I run across to the security room door dodging the bullets but it wont open. I think i have all the PDA'S for clearance but the door still wont open. The keypad panel on the righthand side of the door seems to be damaged. I've tried all around the room but just keep getting killed by turret gun. Can anyone help? who's pda is needed to open this door?
You run straight into the security room through the (broken) window just to the right of the door.
