Okay, so I finished the first mission.. or the second mission. I guess it counts as the first mission, the first one you receive after meeting with the loyalists. I had to save all the time to be able to reload if I fuck up and I had to reload saves a LOT. I managed to finish the mission with low chaos, on hard mode, so I'm pretty satisfied with myself. Found 6/7 shrines, done all the side objectives, explored some, I think I got the hang of it, the powers are pretty cool, I'm curious how things will unfold.
