As much as we’d all love to get another ARG, I don’t believe this to be related with NMS or Hello Games for that matter, Just too broad with finds totally unrelated to No Man’s Sky. Hello Games is not even using the Iam8bit store anymore. I did find some links with discussion to keep informed.
The above post has other links included that may be of interest.
Might be an idea to keep an eye on Game Detectives as their discord has some active discussion about it. Not seen any discussion in the larger ARG communities just yet.
If discussion picks up and appears to be unrelated to No Man’s Sky, it may best fit it’s own topic.
