GURPS Robots, softback sourcebook, by David L. Pulver.
Bold Experiments. Faithful Servants. Soulless Killers.
“You are now obsolete… pray they don’t find out!
A cold-eyed stare from the shadows od the alley… the spine-tingling scrape, scrape as metallic feet drag along the concrete… the squeak and whirr of hinges and hyraulics as the machine approaches. The robot is an intruiging yet sinister being – created to serve, but in many ways superior to its weak and fallible human masters. We need the robots. Do they need us?
This book contains detailed rules for designing, building, and playing robots – from the tiniest nanobots to the mightiest megabots. You can create cyborgs, androids, and even biomorphs – deadly fluid-metal machines that can take any shape.
Use the advanced design rules (completely compatible with GURPS Vechicles, 2nd Edition) to choose everything from frames to power plants to weapons to the tiniest accessories!
Also included are rules for robots as player characters; artificial intelligences and battlesuits; and over 30 completely-worked-out sample robots.”
