Subtitled, "Exploration and Contact Among the Stars"
From the back of the book:
"The Imperial Interstellar Scout Service seeks out strange new worlds within and beyond the borders of the Third Imperium. A scout has to expect the unexpected, embrace the unknown, and master his craft - because the uncharted expanses swallow the foolhardy.
First In gives GURPS Traveller players the information they need on the Scouts' organization, missions, and starships."
