Now the Horrors Have Reason to Fear

When death can lurk around any dark corner, humanity's defenders must be ever-vigilant. Their story is yours, with GURPS Monster Hunters 1: Champions.

Written by Jason "PK" Levine (author of GURPS Psionic Powers), GURPS Monster Hunters 1: Champions gives mighty modern-day heroes what they need to fight the world's most fearsome preternatural foes. This supplement includes:

• Ten high-powered templates for bringing the battle to the brutes and brains of badness. Make psis, sages, and sleuths in mere minutes – building a 400-point hero has never been so easy!
  
• Nine new wildcard skills suitable for any cinematic action game – and expanded rules that make them more useful than ever! Master your chosen field with Detective!, Medic!, and more.
  
• A completely new magic system – Ritual Path magic – that lets casters try any effect they can imagine . . . with dangerous consequences for those who attempt to do too much.
  
• Quick and easy powers – Bioenhancement, Mysticism, and Psionics – that give some champions the edge they need.
  
• Six templates for inhumans. Become a "bad guy turned good" as a lycanthrope or outcast angel.
  
• A selection of gear to arm the monster hunters. You have to buy the bullets before the baddies can buy the farm!

Coupled with the GURPS Basic Set, this pick-up-and-go supplement is all you need to create heroes for any modern-day cinematic supernatural spectacle. The forces of darkness are about to discover that, sometimes, the prey fights back.
