I seem unable to get passed the mission where you have to run to the office and get the key dont no the name of it its a in the same hour as when ur passing through all those air vents and i dont have a clue what to do when i have to go to someones office or something can anyone help ?

That's the one you are playing as Kim.

Once you reach the office floor, there are two waypoints the one to the left of the door is where the key is.

The one almost straight ahead is where the computer room is.

Sneak from the door, to the key, then to the computer room.

But how do i get the key or get into the key room the only way i seem able to get in is by shooting the glass but then i get caught .Thanks CJM News their should be more neo seeker people who are like you

You can get into Tony's office through the door, just take the path to the left from the door you enter the area from. The key is on the desk and you will pick it up automatically.

Take the key to the Computer Room door (straight up if the area door is positioned at the bottom of the screen) and you will be done.

I got a 0% on this mission because I was seen 3 times. No bonus for the 5 head shots with a poor shot like Kim

Thanks

I tried that mission as it is suggested like sneaking around and using air vents. I failed couple times then I decided to be brave and fight even though Kim has terrible aiming with guns. In the end I killed everyone and never went into air vents. Once you get used to Kim it is not that bad. Basically always take cover and aim manually. I think it was also more fun like that, only downsize is (if you care) your mission rating will be low because you will be spotted many times by the enemies.

a boring mission

i did that mission with ease.
