I've only been on the forums for a few months, mostly on the GOW2 and 3 side, but have been perusing the Last Day posts in the last few weeks. This seems like a real fun concept and wished I knew about it 2 years ago. However, I'm still not 100% sure how people found the tags. I've done some research, and thinnk I know, but was wondering if someone could confirm or tell me how.
So, from what I understand, the GOW2 Last Day website and cryptic tweets from SixOkay gave you coordinates to go geocaching. Is this the basics? If not, can someone let me know? I also read that there were videos with clues. Any truth with that?
