You have to consider that the No Man’s Sky community isn’t necessarily the target audience for Waking Titan. Alice and Smith were hired by Hello Games to virally market their game, No Man’s Sky. If all they did was communicate with the game’s fan-base, they would draw in very few new buyers of the game.
The first Waking Titan started out mainly drawing in people from the ARG community and appeared to have no relation to NMS. Then, the ARG suddenly used a comm-ball inside NMS to hide a password and suddenly the NMS community was drawn in, though many insisted it was an ARG trying to hijack the NMS community to drum up interest, which proved to not be the case.
Now, it is quite possible that this AIHBP thing could be drawing interest from many sources, while seeming unconnected to NMS, in order to draw non-NMS fans in again. Also, Markiplier played NMS on his channel, though only for 2 episodes.
I’m not saying it is for sure, but it is still in the realm of possibility that this new ARG is connected.
