Operation Solo Endeavor

Publisher blurb:

This booklet provides additional rules and tables for playing WWII: Operation Whitebox without a Game Master.

Questions are answered using a 1d10 yes/no question and answer mechanic and inspiration prompts for more complicated open questions. The d10 was chosen because this is the default die used for most NPC gut checks, Heroic level hit points, Maquis concealment checks and staffing runs; pretty much all the iconic elements that make WWII games great fun to play.

The book is laid out to follow the mission structure. It has random tables for creating mission objectives and delivering your briefing. There are also plenty of random tables to help you create NPCs on the fly while playing.
