Quick Links
Five Nights At Freddy’s: Secret of the Mimichides a lot of its lore in text logs, found hidden within 42 Mailboxes scattered throughout the MCM Facility. This guide will explain how to track each and every one of them down.
For convenience and ease of reading, thisFNAF: Secret of the Mimicguide has been organized to show the mailboxes in the order they can be first obtained, excluding cases where significant backtracking would be required. Naturally, the game allows a certain amount of backtracking that can enable them to be collected out of order, and only a few mailboxes are found in locations that cannot be reached later on (and will be labeled accordingly in their sections.)
What do Mailboxes do in Five Nights at Freddy’s: Secret of the Mimic?
Mailboxes can be found all over the MCM Facility,and can be activated using the Data Diver to download mail.Once downloaded, you’re able to read the mail at any of the computer terminals found throughout the game. Many of these Mailbox messages provide useful hints and can lead you toward secret locations and collectibles, so finding all 42 can be hugely rewarding. The mail also provides insight into the workings of the factory, the people involved in its eventual failure, and the story of Edwin Murray and his family.
