This page of the Deathloop trophy guide contains a walkthrough of the Violent Delights achievement. From the description below, you will learn how to kill Charlie and Fia with just one bullet.
Trophy description and preparations
You will only have the opportunity to obtain this achievement once you reach the underground location in the Fristad Rock district (in the afternoon) where a pair of lovers, Charlie and Fia, are meeting up. All the steps necessary to unlock access to the underground complex are described in our guide on the Afternoon Delight lead page.
You should prepare in a number of ways to earn this trophy.
We strongly recommend bringing the Sepulchra Breteira sniper rifle with you on this mission, which is the reward for completing the Keep On Giving arsenal lead.
You should also try to unlock and install the Perforator trinket, which allows your projectiles to penetrate through the enemies you hit.
In addition to equipping yourself with the sniper rifle, you should also equip the Aether ability for this mission, as it can make sneaking up on the visionaries much easier.
If you have the Aether ability's Ghost upgrade, then select it. It will give you more time to shoot from the sniper rifle.
Killing Charlie and Fia with one bullet
After reaching the meeting place, start sneaking around and use the Aether ability to help you avoid detection.
We recommend standing behind Fia's back, so that she is directly in front of Charlie, who is standing behind her. Kill the two visionaries early on during their meeting, because otherwise Charlie and Fia will split up, making it more difficult to kill them.
Aim for Fia's head. Hold down the trigger to start loading the sniper rifle (this is a unique feature of the Sepulchra Breteira gun). Wait a few seconds and shoot when the two visionaries' heads are in the line of fire.
