i have only played the games but the whole Metro 2033 mythos is fascinating in the way that it presages this idea that apocalypse will include some kind of very powerful, telepathic creatures who have tall stature, big heads and appear very selectively and carefully

it's not a new story, really, but it's fascinating... i love playing the game, getting immersed in the tunnels and the freezing above ground but i don't think that humans have these stories about this coming doom without having heard them from creatures like the Dark Ones and i think that the biblical Angels are one and the same
