I have been reading what you guys have been posting and have a question as I'm yet to play the game and alert mechanics seems to be a concern:
If I decide to approach missions from distance with a sniper rifle and I successfully eliminate a target, will I be immediately surrounded by enemies because they hear the noise of the rifle or because they find a dead body?
And if yes, will changing position immediately after I fire help to stay undetected?
I'm specifically referring to comments such as:
"enemies being able to magically locate your position 500 meter away if you miss with a silenced sniper shot"
"You can get detected by enemies finding dead bodies"
