It's nice to finally see the world of traveller back in print, this time in the world of GURPS. 1st In is the sourcebook for the Scouts, one of the more interesting settings for PCs. This book gives the readers a look behind the scenes of the Imperial Interstellar Scout Service as well as an extensive background on its organization and functions of each branch. Several sections of the book also deals with world creation and equipment. It's well written and really gives the reader a feel for being a Scout. The world creation section is rather extensive and like in the original scout book(traveller game) can be pretty daunting for the casual gamer. There is also a culture section for those who wish to flesh out each planet, complete with population, type of government, etc., each with explanations on what it means. All in all, much better than the original Traveller scout book and one of the better supplements for GURPS to be published.
