This summer's event was only the first chapter.
Nokia is already planning the next steps for its Conspiracy For Good project, following its debut in London this Summer.
Nokia worked with Heroes creator Tim Kring and transmedia content firm The Opportunity Management Company on the project, which blended video, live events and mobile applications.
"It's a combination of a narrative, ARG, locative gaming and augmented reality gaming," said Brian Seth Hurst, CEO of The Opportunity Management Company, speaking (via Skype) during a panel session at the MIPCOM conference this afternoon.
"We're moving on now to a television series, casual games, console games..."
Hurst also said that the partners behind CFG are already scouting new locations for another physical chapter of the project.
"We're looking at San Francisco, Sao Paulo... we're looking at many different cities," he said. "Now that we've done it once, we know we're going to be able to do it again."
Hurst also put a figure to the number of Conspiracy For Good app downloads this summer. "We did 325,000 downloads from the Ovi Store I think."
How many people actually turned up to play the ARG game on the ground though?
"We really tried to linit it," said Hurst. "We didn't want more than 250 people, and that's what we got. It was really an exclusive ticket. This was a pilot for us."
