Need Help to Start, Cyberpunk themed

[Excession]

Could the zombie plague be something that is infectious through a brain-computer interface? That seems suitable cyberpunk. Perhaps something like:

Society is closing in on technological singularity, nearly post-scarcity, when someone tries to upload their brain into a computer and it goes horribly wrong. Instead of giving themselves immortality they infect nearly everyone else with a magic/memetic/biotech virus that turns them into zombies.

A society reliant on high technology to survive suddenly has nobody to run that technology, and is full of brain-fried but somehow undying zombies. The fall becomes worse, because there aren't huge amounts of workable tech and useful items just lying around; nothing works without the 'net. The players have to work their way through fallen cities and damaged computer systems, infested by both brain-eating zombies and mind-eating computer viruses.

Goals could be:

• Stay alive, short term and longer.
• Rescue, or avoid, other survivors.
• Work out what happened. If the fall was fast enough they might not even know.
• Fix one or more parts of the problem. Maybe they can even cure the zombies.
