The people behind Continuum are running an “alternate reality game” alongside the show. If you’re not familiar with ARGs, it is designed to bring you into the Continuum universe. For a good intro to the game, check out this article by argn.com.
The game will center around various online presences (YouTube, Twitter, etc.) of the Liber8 movement and journalism student Tyler Cross, and possibly others in the future. Your part will be to hunt down codes hidden in posts and videos. Currently, the sites I’m aware of that are or may become part of the game are:
Continuum ARG - website
I’m not going to do all of the work for you, but you can find the first 2 codes in Tyler’s blog entry for May 24th and by checking the descriptions of the videos that Liber8 has posted on YouTube. Enjoy the game, and good hunting!
PS: I don’t know whether Tyler Cross is her real name or if she is actually a journalism student in real life. I’ll be continuing under the assumption that she is an actress hired to play the part for the ARG though.
