The covers are great, especially the very clever use of the back cover. Wish I had thought of that! I like the adventure, the dungeon map is an excellent example of an abstract map, very usable at the table. I like the long dead civilization (Very Pulp/Appendix N) and the environmental challenges that feel logical to the space. A bit confused by the sniper seal haha. But if it felt out of place in the campaign its easy to leave it out.
Would print and keep in my adventure binder. Oh and the stairs in room 6 are brilliant, stealing that idea for home games!
