I'm contemplating on pulling a
System Shock scenario in 2073, as my main player (my fiancee

) is only familiar with the very general outlines of that classic computer game - and not with most of its plot, meaning that I can borrow/steal almost as much as I want from it. I'm cool with WiFi and WiFi hacking, but my main problem with the 2073 setting is that AIs are common and no longer a mystery as they were in 2059. Another problem is that my game is going to be set in Chicago, and there are no arcologies there in canon... Of course, I can add one (hidden in the CZ? by Ares? with Bug experiments?).
Essentially, an Arcology Shutdown scenario requires a rogue AI, mad robots controlled by her, a sealed arcology from which escape is difficult, horrid experiments on humans - and, hopefully, mutants to deal with...
