The Valley Forge
60 years ago an eccentric Billionaire tired of the dog eat dog existence of Mega City 1 started a "simple living" commune known only as The Valley. The residents of The Valley think that they are on a colony spacecraft to a distant planet. They have been living in isolation from other citizens of Mega City 1 for their entire lives. All is well until one of their number finds out the truth and commits suicide by throwing himself out of an airlock.
Phillipe Stark Towers is a 2000m tall luxy block the top 900m or so which are the property of the walker foundation. Entering at any of the pedways or blockparks below 1150m, the PCs will find that the elevators do not have buttons for the remaining penthouse levels. They will need to hotwire an elevator, Barney will be too busy to override an elevator (The control panel is voice activated and will not allow any unauthorised access to or from the upper levels.
The upper levels house The Valley Forge commune, the brainchild of eccentric multi-trillionaire Findus Walker. A commune in which the inhabitants have no knowledge of the existence of Mega City 1, it is an elaborate 60 year psychological experiment to test the theory that the psychological stress of inhabiting a Mega City is the cause of the anti-social behaviour demonstrated by it's residents.
The experiment has been the life work of Findus Smith-Walker who has undergone many bodyswap's in order to witness the result of the experiment at first hand he is currently residing in the body of a 12 year old girl. The residents of the commune live under the pretense that their accommodation is in fact a space colony seed ship destined for a remote corner of the galaxy on a one hundred year long voyage. Many of the original inhabitants who were specially selected for the voyage have since died and their descendants currently inhabit the "space craft".
Oh and just in case you thought the judges were getting off lightly Smith-Walker uses a private army of War-droids (dressed in Judge uniforms) which the residents know only as "space pirates" to keep them under control and at a stable population density.
Suitable Game Systems
JUDGE DREDD RPG but would work in any city based sci-fi setting such as CYBERPUNK / JUSTIFIERS RPG with some major tweaks.
