I'm actually writing a story set in the time of transition between the 'old cops' and the Judges. It's called
NEW CELLS and partly turns on terrorist movements within the USW (United States Of The West--remember that old map?) who are cloning their best operatives. Some of the leading Judges take a keen interest because they've been thinking along the same lines....

I'm firstly developing the idea as the premise of an online role-playing adventure, then repurposing it (pretty much a complete rebuild) as a novella for a future PDF in my
PLAY DREDD DOSSIERS series.
