Tunnels in White is a crisp adventure with three clearly delineated factions and no defined "right path" which I really like. The Doom Clock especially stands out, things get real bad if you do nothing or fail to hinder certain parties. Also SPACE CRABS!
With the materials and background provided, this one would be pretty easy to run after you give it a read. Good as a shorter mystery mini-campaign but one could easily imagine the fallout of its conclusion.
I've been following Christian's work for some time and so definitely came for that Dextro-Singleton DEEP LORE which now spans centuries? millennia? You do not need to know or have read any background materials for this adventure.
