I am having trouble in the escape level. How do I get Jane Wilde off the..

After hours on top of hours trying to figure out how to get off the roof with Jayne...I figured it out. DO NOT hang off the roof and try to shimmy across to the other balcony! Go down the ladder to where the double doors are locked on that balcony. Then get up on the ledgeto your right when you reach the bottom of the ladder. Face the wall and push your z button to walk the ledge. Slowly keep moving in the direction of the balcony at the far end until you get there. Go through doors and there will be a guard...kill him. Around the corner there will be a few more...kill them! Then the patient will give you the key to the locked double doors. After that head to the room and unlock the doors for Jayne. You craw through the elevater and push the botton to let Jane in and you will then reach you next chack point in the game. Leave Jane in the hall way while you take out the four guards at the end of the courtyard. Climb the ladder and kill the guards at the other balcony. Then go get Jayne and have you follow you. Once inside the green door , there will be one guard around each corner until you get to the end of the tunnel to escape.
