From publisher blurb:
Myths of the Far Future is the overall title for EN Publishing's "sci-fi D&D" ruleset. It includes a default setting, but is also designed to allow you to create your own myths of the far future. Using the rules presented herein, you should find enough information to pay futuristic characters in any far future setting of your own making.
THIS IS THE D&D 4E VERSION OF THIS PRODUCT.
Welcome to the Myths of the Far Future Campaign Guide. In this campaign, the heroes will take on the role of bounty hunters who find themselves challenged across eleven adventures spanning levels 1 to 20 in a search for the legendary bandit. They will travel to different galaxies and worlds within each sector, battle outlaws, face off with rival bounty hunters, and encounter several alien species. The party will also need to forge alliances, however shaky, and gather what little information they can in order to succeed.
Consider this guide a Dungeon Master’s overview of the campaign, the characters and locations involved. To get the most from the rules found within, you may also want a copy of the Santiago Player’s Guide, the D&D 4E Player’s Handbook®, the D&D 4E Dungeon Master’s Guide®, and the D&D 4E Monster Manual®. Additionally, the D&D 4E Player’s Handbook® 2 and the D&D 4E Adventurer’s Vault™ provide useful expansions to provide even richer immersion into the world.
If you are a player, we highly recommend you don’t read any further. Any rules material you need is presented in the Santiago Player’s Guide, available separately.
