From the campaign:
Players take on the roles of sleeper agents created by secret projects during the Cold War, placed in cryo-sleep in anticipation of nuclear war. Now they are waking into a 21st century that has forgotten them, a world imperilled by other long-hidden dangers such as weapons stockpiles, biowarfare experiments and other sleepers turned very, very bad.
The player characters, under the aegis of the secret organisation Obsidian, execute missions against foes ranging from crazed sleepers to the remnants of WWII’s bioweapons project and conspiracies within modern-day governments. They are assisted in this by the superhuman powers with which they were imbued by the projects that created them, and by an armoury of advanced gear that grows as Obsidian researches new technologies.
