From publisher blurb:
Combat Walkers are the precursors to modern battledress, and for a while, exist alongside the smaller suits as heavy fire support. This micro-supplement for Traveller, written by the author of 2300AD and Traveller Supplement 5-6: Vehicle Handbook, examines a special-purpose combat walker called the Cyclops. The Cyclops is designed for littoral (shallow-water) environments, and serves as heavy fire support for troops along the shore.
This book includes stat and details on the Cyclops, along with two variants, the Cyclops Mk2, and the Polyphemus. Additional information is provided on new vehicular weapons, new skills, and a new robot, the Attack Remote-Operated Vehicle.
Three adventure seeds complete the book, each with detailed world map and adventure notes.
