Snipe the snipers before they snipe you. Once you start shooting, the sniper timer will count down fast so you may want to try and remember their positions if you can. Watch out for the sneaky soldiers that move in and out of cover.
As a hired sniper, we expect efficiency and confidentiality from you. You will be marked on the accuracy of your marksmanship in all the missions and your ability to remain undercover throughout the mission.
