- Go to your in-game settings, go to "game", and turn off the tutorial option. [VERY IMPORTANT]
- Play Mission 1: Prologue.
- Kill Von Eisenberg, and DON'T kill any other soldiers (unless you can hit every single shot).
- Just run to the next objective, you will be standing on a balcony, shoot the two soldier in the yard.
- A tank will come riding through the wall, just ignore it and DON'T shoot the tank (shooting the tank will count as a missed shot), go to the next objective and crawl inside the house.
- You will have to cross the road, but there will be some guards outside. Just run past them and don't shoot at them (unless you will hit all your shots).
- When you go inside the other house and run upstairs, there might be a soldier. If he blocks your way, shoot him, if you can run past him, run.
- You will end up at another balcony, don't shoot the soldier down there (unless you will hit all your shots). Just run down there and finish the mission.

Good luck with getting this achievement!
