Dig

I’m surprised how much I managed to progress without a guide, considering how unhelpful the game is.
We revive Brink, the archaeologist that falls to his death early in the game, and he gets obsessed with the crystals we used to revive him, as well as some ancient machine, so he isn’t much help at all.
The only puzzle I kind of remembered from reading about the game was recreating the turtle. You have fossil in one room, and bones you can place and rotate in the other.
There is a lot of find password, go back to nexus, open new door. And at one point, you just have to try all the passwords you have acquired in order to proceed.
