Mission one guide:
First only buy the sniper rifle because this is the only thing you'll need in this mission.
Of course you'll begin at point A ,the fastest and safiest way is to use the western rooftop ( B ) as your sniping point.
Use the elevator to reach the top and go to the edge.
Now you can grab the sniper rifle out the suitcase but maybe it's a little cool to wait when your target arrives and then equip the rifle.
While you wait (couple of sec) there will be a small cutscene that shows the Blue Traid member exiting his car.
A couple seconds later another short cutscene with your primary target will be shown.
Now wait till your target gets in view and take the shot (view the bottom image to see location).
Then run straight back to the elavator and go down.
When down run or walk back to your car (A) to end 47's first mission.
Note: the target will move his head while talking to the Blue Traid member so don't waist the only bullet that you have.
After taking the shot the game will note you that your target is dead by giving a message at the above left corner on your screen or
that the geards heard a dead scream or by viewing your laptop.
Note: when you killed your target a helikopter shows up that was patrolling the town to check out the gunsound.
It will fly straight towards you so don't act as you want to flee from the scene because you took the shot.
As long as you walk normal back to 47's car there's nothing to worry about and they will never know what hit'em.
