Just a short note to say that it is possible to do this without picking up any armour, plus getting the achievement for completing a level on 007 classic difficulty without using armour. The reason for this is i hadnt a clue where any armour was. I just ran through the whole level barely stopping at all and anyone that got in the way , just melee them as i found this was quicker than shooting
Idid die a few times but this is ok as the timer just goes back to where it was when you pass through a checkpoint.
One word of warning is when you get in the building that you jump from, shoot the guy stood in front of the door where you make your escape. The reason for this is that there is another guard stood to the right of you, and if you tried to melee the door guard, the second one will kill you.
