S.T.A.L.K.E.R. 2: Heart of Chornobyl

Towards the end of the game, you'll reach the Subtle Matter main story mission in the Burnt Forest where you need to make key decisions to choose the ending of the game.

There are four main endings to the game, each with an associated achievement:

• Brave New World
• Project Y
• She Will Never Be Free
• Today Never Ends

In order to unlock Alas Poor Yorick, you need to avoid the Today Never Ends ending and take one of the other three paths.

• Brave New World
• Project Y
• She Will Never Be Free

If you are planning on unlocking all four endings, then no particular effort is needed, as this achievement will be unlocked by three of the four possible endings.

To meet Scar, you must select life is for living during Subtle matters, this will set you on the path to fight him regardless of other choices.

Here is a video of how to defeat him


He is one of the easiest bosses Do not engage when his shield is up, instead find the 3 terminals on the edges of the room.

Hit the button when he is front of TVs, this will stun him and allow you to attack.

I needed to do this 3 times and he will die.
