Easy "Long Shot" and "Marksman...
	Easy "Point Blank" achievement...
	Various Achievements...

First, buy and equip a x10 scope in the safe house. This can be done after the first story mission. Interact with the weapon cache in the safe house to buy and attach the scope. In the game options, enable "Aim Assistance" and "Sniper Red Dot Aim Helper". While holding your breath, it will display a small yellow dot. This dot marks where the bullet will hit. The dot turns red when it is going to hit an enemy. Go to the location in the video, lie down, aim at the enemy, and hold your breath. Point the aim helper at the enemy's head and shoot. You may want to stand very close to your screen to see the head. If you do not get the "Long Shot" and "Marksman" achievements, quit out to the main menu and select "Continue". It will make the enemies respawn (but only if you have not cleared out the entire enemy base)

Sneak up to an enemy from behind (unnoticed) and kill him with a shot from the sniper rifle from three feet or less to get the "Point Blank" achievement. Once the takedown/interrogation prompt appears, you should be close enough. This works well on lone enemies such as snipers. It can also be done on the first two enemies in the prologue.
