The '''newsletter''' is a mailing list by [[Cardboard Computer]], initially made available to players who had purchased the game. Instructions on how to sign up to receive the newsletter are located in the game's installation folder. In November 2018, Cardboard Computer announced in a public [https://www.patreon.com/posts/22489303 post] that the newsletter had been "largely superseded" by their [[Patreon]], posting a link to an archive of the previous issues.
The newsletter archive can be found at http://kentuckyroutezero.com/pub/newsletter-archive/.
