Our Hell is Us Research Guide tells you how to unlock research, how the research system works, and how it can be used to find Vaults of Forbidden Knowledge.

How to Unlock Research
You can unlock the Hell is Us research system by traveling to the Vyssa Hills Location and talking with the journalist Tania Alver. "Research" is the last tab on your Datapad that is locked at the start of the game.
First, you'll have to complete your core objectives in Senedra Forest, the first Location of the game. That will give you access to the Acasa Marshes. You must then rescue Victor Gaz, which unlocks the ability to upgrade weapons and Defensive Gear.
Once Victor is rescued, he'll unlock the ability for you to travel to Vyssa Hills on the map. You can then travel there and explore; you'll eventually meet a man named Vitalis who will point you toward Tania Alver. Tania Alver is in the same Location, and she will join you in the APC as a traveling researcher helping you with your mission.
How Hell is Us Research Works
Hell is Us research is a system that is used to unlock Vaults of Forbidden Knowledge throughout the land of Hydea by scanning Research Items. These Vaults, in turn, will have Glyphs, Relics, and other useful items inside of them that will aid you in your quest.
As you explore the world, you'll come across Research Items. Give these Research Items to Tania Alver in the APC and she'll find out more details about them for you. Each item she researches advances a tracker toward unlocking the next Vault of Forbidden Knowledge. When you research enough, you'll get the Vault's combination and location.
Below is a list of every Research Item we've come across in the game thus far and an explanation of where you can find it.
