How do you access the server in splinter cell 3d on displace

its tricky if your not careful (very easy for me). the entrance inside is down into the air vent from the roof. the air vent stops over a room. DO NOT go down there yet. but get close enough to the edge and you will see the suitcase by the table those to guys are sitting at. you can hack it from there without any risk (unless you fall in the room like an idiot). if your not fast enough the two guys will leave the room and its hard to get another good chance to hack it from there. once they leave the room follow them. remember to keep your distance and stay in the dark. its too risky to try and mess with them so leave them alone. the door code out of the hallway is 8136. follow them into the lobby let them talk and go away. dont go past the window or they will see you. after the leave disable the camera in the lobby and move to the other side. at the end of the lobby there are two glass doors with a gaurd with a gaurd sitting behind the desk. dont go after him either. on one side of the doors whistle to get his attention and then quickly go to the other side quickly and quietly, if you do it right he will come out and investigate the spot on the other side of the doors where you whistled. quickly sneak up and grab him, then take him to the retinal scanner behind the desk and select: use retinal scanner, he will unlock the door. DO NOT let him go. past the door you unlocked there is a hallway with invisible lasers in it.( use night vision and you will see them. the same thing goes when your leaving the vault at the bank). carry him across and knock him out. there is another door at the end of the hallway. go inside and you will find a save point. use it if you like. in the next room there is a guy at the computer. wait for him to leave into the next room. follow them and throw a flashbang in there. then knock them out while they are stunned. the next room over is a firing range if the gun is on, then turn it off and go to the end of the range where there is a vent go in there and travel to the end of it. when you get to the end climb out of the vent on the rope and you will be in the server room use the algorithm on the computer, access the computer, and GET OUT through the vent. or the power will come on with you inside, the to guys in the hall will have access to the room, they will see you and kill you. dont think you can hide because the room is too bright, trust me ive tried. good luck
