13 Sentinels Aegis Rim: How to Unlock Mystery Files

Developed by Vanillaware and published by Sega, 13 Sentinels Aegis Rim is a real-time strategy RPG that certainly serves as a pretty radical departure from the studio’s previous works like Dragon’s Crown and Odin Sphere, which were both robust action RPGs. This game also has a much heavier focus on story as compared to the past releases. Here’s how to unlock mystery files in 13 Sentinels Aegis Rim.

Unlocking Mystery Files in 13 Sentinels Aegis Rim

If you just play through 13 Sentinels Aegis Rim normally, going through both the story and combat sections, you should be able to glean most of the plot and what’s going on in the story that way. However, Vanillaware has designed the game such that a lot of the deeper lore details and world-building information have been locked away in mystery files.

If you really want to get to know the world in 13 Sentinels Aegis Rim, you’re definitely going to want to look into unlocking the mystery files as you play.

These can be unlocked in a variety of ways, as listed below:

• Clearing battles for the first time.
• Clearing story sections.
• Completing bonus objectives in battles.
• Getting S ranks in battles.

You should be able to get a good chunk of the mystery files just by playing the game naturally, but if you want to collect all of them, you’ll need to go above and beyond.

The best way to collect them is to check the bonus objectives for each battle. Some of these are simple, such as having a specific character on your strike team for that battle, and others are harder, such as having to clear a battle within a time limit. Either way, completing bonus objectives is a good way to unlock more files.

You’ll also want to aim for S rank completions, which require you to get high hit combos, while also avoiding damage and immobility as much as possible when fighting.

To view your mystery files, simply press the R2 button while outside of combat and the Destruction menu to bring them up.

From here, you can take a look at all of the files you’ve unlocked so far and read through the information they contain.
