Indecent Proposal

So far, I found that there are 2 Guards. When you have the Main Guard Distracted, you can move inward, you will come to a guard with a torch, hide on the right side of the big rock in the middle area, wait until the guard walks back and then forth to his main standing place, as he walks back, slowly move around to the back of him and press the button required to quitely kill or knock them out. I haven't worked out how to pass the guard who is urinating near the door, which maybe a throwing knife would be good here. i am going to try this. As you get half way from the corner towards him he instantly turns around, so we have to get rid of him before getting close to him.
