NPC and Map artwork are in a seperate Zip file, and the module comes with the playtest version of the rules for 5e. The maps are great, with a different stylized map for players and GM for the bulk of the module.
The role of "event coordinator" is great, and should be a success for any large group, but the module also appears to be easy enough to run for just a single table without the event coordinator. The event coordinator adds to the experience, but not to the story.
The module itself is pretty much a railroad dungeon crawl, although how the dungeon is explored is very open, and it's likely that the group will not find everything on their first run through (assuming they survive to the end)
Mosters in the module are different from those in the original playtest package, however the module wars that the monsters are still in "playtest" mode, and not finalized. Combat difficulty can vary dramatically between monsters, and players, so a DM must gauge the party carefully. Though the module is designed for levels 6-8, I found it is very easy to increase or decrease the difficulty for other level ranges.
