A two mission campaign, the first a well made city, with lots of exploration, in combination with verticality. Within the City there's an immense Hammerite Cathedral, again superbly done, but the FM really comes into it's own after you get into the titular Catacombs.

There are shades of the Bonehoard here with many (many!) undead enemies, and Burrick tunnels. It's incredibly well designed,and the atmosphere is top notch. There are puzzles to be solved almost everywhere you look, from "where can I stand to avoid this trap" through to some that require a little thinking and looking around at the environment, and then there are some that are just plain tough! (I'm not ashamed to admit that I needed a hint!).

Some surprises made me jump, and I was on edge nearly the whole time. Every now and then I would find a dark corner and take a breath.

There are some things that didn't work; I got stuck, unable to move a few times having to reload, and I believe that some enemies respawn in some areas. I'm not used to that.

Overall though it didn't detract from what is a great mission, if you like undead missions go play it, if not, heck go play it anyway!
