Video starts about 10-15 minutes into the panel session. Left-most guy is James Frey, the lead on the project. Right-most guy is creating the puzzles, and second from right is John Hanke from Google and Niantic (creator of the mobile phone game called Ingress). The story was explained before I started recording - the recorded bits are explaining how the Endgame media empire is working and planned to work.
From memory: Before the video starts, James is explaining Endgame. He says the human genome project found that the human genome was modified inexplicably 12000 years ago. Also around then, humans started building civilizations around gold mines, and became obsessed with mining gold, even though gold is not useful for making weapons or anything practical at the time. Also, he says there is a pyramid in China which is "exactly" 3x the size of another pyramid somewhere in Egypt or central america, can't remember which. Also, both pyramids are coated in the same material, and are (or were) capped with gold. Also, many of the world's religions were formed around that time, and they have common bits about the end of the world. So he's creating endgame to be a fictional explanation for that.
The fiction of Endgame is: aliens conscripted humans to mine gold for them, and promised to return to earth. There are 12 human civilizations which have been training generation after generation to be ready for this. Upon the alien return, fighters under 20 years old from each civilization must begin the Endgame, a battle royale. The civilization of whichever fighter survives, lives. Other civilizations are wiped out.
