The whole plot really depends on it, so if the answer is poor, that's it for the game's story :lol. I mean, when I saw the presentation, I didn't even pay much attention to it, because the world and the enemies looked so cool, but the time I stopped to think about, I was like wat. I really wish that the game will give detailed information on how every energy source just "ended", considering that we already know so many alternative ways to produce energy. Judging by the city they showed at the beginning, humanity probably had that knowledge already by the time it all went dark.
edit: @nib95 and Raven Prime: how come humans vanished if all those types of energy sources are suddenly viable? If humanity crumbled because the machines turned against them (which is the most used cliché in the book, aside from zombies), it would be understandable, but stating that the world went dark and humanity died because of it is quite weird.
All I can make out from the trailer is that "a darkness came", that could mean anything.
