About Universal Machine

RedCogUniversal Machine Publications was set up in April 2014 to produce Open Game Content  (‘OGC’) material for science fiction roleplaying games under its own ‘2d6 Science Fiction System Reference Document’ (‘2d6 SF SRD’), which is published under the Open Game Licence version 1.0a (‘OGL’) by Wizards of the Coast, Inc.

The 2d6 SF SRD is continually updated with new rules and material and is fully compatible with the Traveller System Reference Document version 1.1.
