I actually did manage to finish it, but it gives no added context for the new trailer anyway. I liked the endings but the “morality” system to get them is also the worst of the series, and boils down to whether or not you handle two forced combat/stealth encounters non-lethally unless you go out of your way to kill literal slaves for zero reason or reward. The enemies in those encounters are the same generic ones from the rest of their chapters, and they put that importance on playing non-lethally with 0 non-lethal weapons to use in an FPS. The entire game is half-baked ideas.
