This is a well organized and clearly written module. The table of contents, map, factions section, etc. all make for an easy to use adventure for the referee.
With regard to the mission...I like that the FIST team doesn't really know all that is going on...the unknown contents of the container, the cult...cool set up. There are multiple ways the team could go about tackling this mission and a couple of options for how it will end.
Would definitely like to try this one with my group.
