How to Unlock Every Mystery File in 13 Sentinels: Aegis Rim (Analysis: Complete Trophy)

13 Sentinels: Aegis Rim

In 13 Sentinels: Aegis Rim, you will collect Mystery Files, which give you small tidbits of information about various things you’ve seen and done, or people who you’ve met. If you get confused about the various names or items in the game, Mystery Files should help you stay oriented.

There are 250 files in total (including the 000 file). If you can collect all 250, you’ll earn the Analysis: Complete Trophy (and on the road to Analysis: Complete, you’ll also earn Analysis: initiated for 20 Mystery Files, Analyzing… for 100 Mystery Files, and Still Analyzing… for 200).

There are different ways of earning and unsealing Mystery Files. Some will be unsealed naturally through story progression, some are unsealed by completing objectives in Destruction, and others will have to be unsealed manually by spending Mystery Points (MP). Mystery Points are earned in Destruction (if you want to earn MP fast, check out my MP guide).

Once you unseal all of the Mystery Files, you’ll pop the Analysis: Complete Trophy.

Below you’ll find a complete list of memories in 13 Sentinels: Aegis Rim, along with information on how each one is unlocked.

Just a brief warning: Some of the titles of Mystery Files (and events) might be light spoilers, so proceed with caution.
