.. What is there to learn from the archives?

The archives are rather confusing; every time you click on a card, all the other cards shift around, which makes it hard to keep track of which ones you've looked at and which you haven't.

In general, the green cards give information about people and the white cards tell you about Revenant and the Colony operation. Try to read all the cards that are currently available; some of them are important background information, some of them are just ... chilling. How do they know so much about you and your friends?

One of the cards is nothing but a couple rows of symbols. Take a picture of that one with your phone; you'll need it later.

What do I do with this row of symbols?

As for the locked cards, you'll need to track down the passwords for them as you go along in the game.
