“Welcome to ZERO PROTOCOL, where codes, puzzles, and grids await! This guide is here to provide hints and nudges for solving puzzles, but also includes spoiler-marked answers for when you’re truly stuck. Endings are also achievable with the help of this guide, but don’t worry – no details will be revealed. Keep an eye out for secret notes that can only be read at certain levels of sanity and remember, you can shoot off padlocks. X’s on grids indicate what to fill in and I’ll do my best to describe rooms and objects without giving away puzzle solutions. Let’s get to it!”
