A good add-on to a great game. If you liked the mystery unraveling and sleuthing of the base game, then this has a whole lot of it. Unfortunately for me it started to feel very tedious, and I didn't feel it was very worthwhile to finish. It's very dense, and maintains a good atmosphere, but I personally got kind of bored of trying to do the same few sections properly within the specific timeframe while it was available and having to reset. I'll likely go back and finish it at some point in the future.
