Level One: Trouble in Paradise 

Armory key card:
In the first mission there is a locked armory to the left if you went in the front door. It 
contains grenades and a bazooka.  To get the key card enter by using the claw on the vent outside,
at the end of the catwalk you will drop down and see a guard facing away. Drop in, get right on 
top of him and hit him with your fist, he should go down in one or two hits and you will get the 
key card if you're close enough.

Use the Q-decrypter on the front door, but before it opens use the Q-claw on the vent on the tower 
above the building. So the camera will not see you, but you will get extra points.  Do not open the 
door as it alerts the guards.

On the first level when you come to the sub pen the sniper on the second floor is concintrating so 
hard you can come up within arms reach behind him and kill him how ever you like with ease. If you 
get right up to him he will sense you and look up. And even if you put a silencer on your pp7 the 
sub launch starts and the other guards suspicion will arise.
