Face it, everybody loves a game with a new idea, and Murdered, Soul Suspect was definitely in that camp. It's not that it was a horrible game. The story was decent, the acting was decent, but the game play felt forced and annoying.
I played it all the way through. I think it was written pretty well as a story. But when you find yourself annoyed by having to fight through scenes with demons that are pretty much all the same, and go over the top to try to be frightening with the music and the screams, it breaks the story up and has no need. (I understand why they did it... How else are you going to threaten someone who is already dead...) But it makes for a disjointed story.
The rest of the game play was reasonable, but poorly executed. You struggle to get the right camera angle so that you can inspect certain objects. And your pathways are always blocked with mystery ghostly objects that make very little sense.
Maybe rent it if you like ghosts, witches, and cops, but don't expect it to live up to the hype.
