The folks at Funcom have something big planned for
The Secret World on December 21st, 2012 and are launching an
alternate reality game (ARG) in and around the game to support the event. There's not a lot to go on right now but they have launched a
sign-up page where you can register to get more information.
It's been a while since we've seen a good ARG in the gaming community and I'm intrigued to see how Funcom pulls this one off as it looks like they might be using content both inside and outside the game. Given that the game is built around these kinds of thing I'm kind of interested to see if this is the start of something new for them.
