This is my run of Styx: Shards of Darkness in co-op mode on Master difficulty. In addition to that, we went for the Mercy (No Kills) and Shadow (Never Detected) Insignias alongside all optional objectives*.
Feedback is welcome in the comments section - let me know if you would like to see more co-op walkthroughs in the future.
----------
* In this video, I didn't really complete all side objectives, because it would have failed the no-kill insignia. However, I do show a very quick and easy way to do it at 9:15, just release the chandelier when Barimen is below it. I wish there was a non-lethal alternative for this objective.
