Key Code

Before you rescue the ambassador in the train, you 
will come to a key code input lock. At the end of the
 hallway with the lock, there will be a door, if you 
go through the door, it will have a memo, pick it up, 
then press "Start" go to "Items" and click on the memo" 
do not click "Use" instead, click "Check" then the key 
code will come up. But, if you are in a hurry and don't 
want to go get the memo, the code is 1742. But first, 
go up to the door and when the triangle flashes, press 
the triangle button. It will switch to a 1st-person view. 
Look to the left, there will be a guard there. This 
might save you some life, instead of just unlocking 
the door and rushing in and getting shot. After you 
kill him, go into the door on the left, I won't spoil 
it for you by telling you what comes next. :)
