Delta Green: Agent's Handbook
Dennis Detwiller, Christopher Gunning, Shane Ivey, Greg Stolze


Born of the U.S. government's 1928 raid on the degenerate coastal town of Innsmouth, Massachusetts, the covert agency known as Delta Green spent four decades opposing the forces of darkness with honor, but without glory. Stripped of sanction after a disastrous 1969 operation in Cambodia, Delta Green's leaders made a secret pact: to continue their work without authority, without support, and without fear. Delta Green agents slip through the system, manipulating the federal bureaucracy while pushing the darkness back for another day--but often at a shattering personal cost.

In Delta Green: The Role-Playing Game, you are one of those agents. You're the one they call when unnatural horrors seep into the world. You fight to keep cosmic evil from claiming human lives and sanity. You conspire to cover it all up so no one else must see what you've seen--or learn the terrible truths you've discovered.

The AGENT'S HANDBOOK is a players-only rulebook for Delta Green: The Role-Playing Game. This new incarnation of the award-winning DELTA GREEN game line includes:

  • Rules for creating agents of all types.
  • Rules for tense, fluid investigations. Players who use their agents' skills in clever ways have the best chance to succeed -- and survive.
  • Nerve-wracking rules for combat, where random disasters can undo the most careful planning.
  • Mind-melting Sanity rules that see agents gradually deteriorate -- and sometimes snap.
  • Rules for "home" scenes where players see what their agents are fighting for.
  • Quick, intuitive rules to determine equipment and assets.
  • Dossiers on the federal agencies most likely to be featured in play.

Further terrors can be found in the forthcoming core rulebook of Delta Green: The Role-Playing Game, which will include everything from the AGENT'S HANDBOOK and massive resources just for the Handler.

Sects of the Martial World: Temple of the Jade Mercies
Brendan Davis

A Temple of Supreme Hypocrisy

Temple of the Jade Mercies is a new Martial Sect for the Wandering Heroes of Ogre Gate roleplaying game. To the outside world, the Temple is a place of contemplation and compassion, but behind their walls beats the heart of a vast criminal network. They are a den of cruel and greedy tomb raiders led by the pleasure seeking Grand Abbot Lao and his greedy right hand man, Smiling Abbot. The monks and nuns of the Jade Temples offer lay people mercy with one hand and steal with the other. They do not need to beg when they can take what they desire. Aided by a group of bandits called the Blades of the Lotus, they attack caravans and plunder graves for artifacts to sell on the black market. It is better to join the temple than be a victim of its excesses.

This PDF includes stats for members of Temple of the Jade Mercies and The Blades of the Lotus, new objects and weapons, and new Kung Fu Techniques. It is designed to be dropped into any campaign as needed.

Orbital 2100
Paul Elliott, Ben Lecrone

Orbital 2100 is a science fiction setting for Cepheus Engine and other Classic 2D6 SF games. It has a realistic (TL 9) feel that is set within our own solar system. The Earth us locked in a Cold War with the people of Luna. Both face off, 400,000 km apart, threatening mutual annihilation whilst they compete to colonise the moons of Jupiter and Saturn. Older colonies such as Mars and Mercury are independent and caught up in this struggle for solar system supremacy. Spacecraft use nuclear thermal rockets and create gravity by spinning pods or centrifuges, this is spaceflight as envisaged today!

In keeping with the near-future and hard-science fiction themes, role-playing campaigns focus on real people doing real jobs. The game has rules, technology and advice to allow scenarios based around deep space haulage, asteroid mining, salvage, rescue and exploration.

Should the referee and players decide to stick with the default campaign premise for Orbital, then the player characters will be spacers, the rough and tough crew of a deep space vehicle owned by a corporation that leases its spacecraft out to agencies, individuals and corporations. Like the crew of a salvage or heavy lift ship today, the characters will find themselves engaged in diverse, challenging and dangerous jobs with every mission.

One month may involve dropping a cargo of habitat modules into the Martian atmosphere, a few months later it could be salvaging a robotic drilling rig in the asteroid belt that has come to the end of its useful life. The emphasis is on 'being in space', working in space and dealing with all of the challenges that operating in the solar system throws at them. The referee can put all kinds of obstacles in the way of PCs, making the outcome of a mission always uncertain. It will be ingenuity, resourcefulness, skill and bravery that will see them right in the end -- or alternatively, asphyxiated, frozen, irradiated, boiled, depressurized or out of a job!

Requires the use of the Cepheus Engine or other Classic 2D6 SF rules-set.

Microscope Explorer
Ben Robbins

Microscope Explorer is a supplement for Microscope, the award-winning role-playing game of epic histories.

The new book is loaded with tools and strategies to get the most out of your Microscope games. One of the biggest challenges is picking an idea for your history: the possibilities are nearly infinite but game time is not. Microscope Explorer includes new step-by-step SEEDS to get you started playing more quickly. Want something novel to spark your imagination? Roll on an ORACLE to generate a random seed instead.

Explorer also lets you use Microscope in entirely new ways. It includes three spin-off games, each based on the core principles of Microscope but with careful adjustments to create different experiences:

UNION transforms the normal Microscope history into a family tree. You go back and fill in the blanks to explore the lives of the ancestors whose unions brought each new generation into existence.

CHRONICLE focuses and streamlines Microscope, narrowing the history to the story of a single thing, such as a building, a city or a ring of power. It also brings individuals to the forefront of the story with anchor characters whose lives are intertwined with each chapter of the history. It's a simpler, more personal, Microscope.

ECHO lets you muck around with alternate history and cause-and-effect. Travel back in time and change a single moment and see how that change would echo forward, reshaping your history or utterly destroying it.

There are also techniques for using Microscope for WORLD-BUILDING, rules EXPERIMENTS and more.
