About Dual Protocol Guide

Dual Protocol Guide is an unofficial help desk for the two-player noir puzzle game DUAL PROTOCOL: The Case of Eva & Miles. It is written for pairs who want a nudge without having the whole Castellari case spoiled, and it has no connection to Aegean Crafters or Rock Paper Publisher.

The Night Desk is the small team that keeps this site. We read the Steam store page, the developer announcements and the Steam discussion threads for Dual Protocol, and when two sources disagree we print both and say which one we trust.

Where the numbers come from

Every fact links back to where it came from: the Steam store page, the developers' Steam announcements, or a named Steam discussion thread. A puzzle answer only one player has reported is labelled as a single report until a second source agrees.

How often it changes

The launch and co-op pages are rechecked the day Dual Protocol releases and after every patch note the developers post on Steam; puzzle pages are added as each chapter is confirmed.

Things we refuse to post

No guessed codes, no leaked or datamined story spoilers, and no puzzle solutions presented as certain when the launch build may have changed them.
