Here's the first video for an upcoming Activision game (probably
Singularity) that raises the creep factor quite a bit. The video talks about a mysterious Russian island that may have been the home for secret Russian experiments during the Cold War. There's a
website that goes along with it so if you've got some free time it might be worth checking out. Personally I'm a bit over the viral marketing/ARG campaigns for game but this one does seem fairly interesting..
