Six Guns is a science-fiction roleplaying supplement using the Traveller rules from Mongoose Publishing. Each issue presents six examples of the topic at hand in detail, with accompanying notes and stat blocks.
This issue's topic is not a type of equipment, but a set of organizations that provide emergency relief and disaster response. While specific names have been associated with these companies and agencies in the body of the descriptions, and some flavor details provided are specific to the Twilight Sector Setting, all of the following should prove suitably flexible to insert into any Traveller game, regardless of setting.
Note that all features, rules and special effects contained in this supplement are subject to the approval of whoever runs your game. There's nothing game-breaking in here, but neither is it carved in stone that these items must exist in your game universe. And remember... if you're allowed to use it, then the opposition can use it too.
