Be Afraid of the Dark
The Sixth World is full of dark crevasses and corners where people can hide. Where they can go when the rest of the world has told them they don’t belong. Where they can be forgotten. People who disappear into these places become secrets, whispered threats of a mysterious something that lurks just out of sight.
Some people—the normal ones, the sane ones—avoid these dark corners and any danger they might be hiding, but shadowrunners don’t have that choice. The dark corners are where they live. So when Mr. Johnson needs some information that’s hidden in one of these places, you know that he’s not going after it himself. He’ll send some runners instead and let them deal with whatever might be waiting for them.
SRM 04-06: Hard Target continues the ongoing series of Shadowrun Missions, further entangling runners in the hunt for powerful artifacts in Seattle. Whether you’ve played through all the Missions in this sequence or you’re coming into the storyline for the first time, Hard Target gives players the chance to dive into Shadowrun and confront the creatures that live in the Sixth World’s night.
SRM 04-06: Hard Target is for use with Shadowrun, Twentieth Anniversary Edition
