How to unlock the Morpheus' Blade achievement in Styx: Shards of Darkness - Definitive Guide
There are plenty of guards all over that are sleeping during missions. You will see "Z"s floating in the air by their head. Simply go up to any of them and take them out. You can unlock this as early as the first mission Prologue. Just after hearing about a secret room in a guard conversation (you can't miss it) you will proceed upstairs. There is a guard bunkhouse on the second floor where one guard should be sleeping standing up. You may have to reload a Quick Save to make him fall asleep. The trophy will unlock immediately when done correctly.
This achievement is very self-explanatory. Throughout the game, you will often come across enemy guards who are taking a nap while on patrol. They are usually found standing upright against a wall or post and you can tell they are sleeping by the "ZZZ" above their head.
Once you've spotted an unarmored guard who is sleeping (there are a few in the Prologue), approach them quietly from any angle and then perform a muffled kill with your dagger by pressing and holding . Once the sleeping enemy has been killed, the achievement will unlock.
