After finally meeting up with the Doctor, Skif discovers a wounded Strider at his doorstep towards the end ofthe Dark Times main mission inStalker 2. After having a long conversation about Strelok, the Doctor asks Skif if he can retrieve a Monolithian device that could save Strider’s life, thus starting An Act of Mercy main mission.

This mission is quite straightforward, but there’s a special objective that can make things a lot harder for players. Players will also get the Whip unique rifle as a reward towards the end of the mission.

Finding the Monolithian Device in the Cable Tunnel

Once the conversation with the Doctor concludes, head over to the Cable Tunnels location toretrieve the Monolithian device. Once you reach the building, go inside and start descending the lights of stairs until you reach the lowest level. Now there will be enemies ahead, and you must not kill them to fulfill the Doctor’s optional request totake care of enemies non-lethally.

Although shooting enemies in the leg will take them down without killing them, it will still mark the Doctor’s optional objective as failed. So, even if you shoot enemies in the legs to incapacitate them, it’ll still count as a kill, rendering the special objective failed. Make sure to stock up on a lot of medkits to keep restoring HP as you run past all the gunfire.
