Yeah, for some reason that channel just re-uploaded the old video from around E3. It also says there's supposed to be a new trailer on 8/20 but AFAIK that didn't happen yet. There's just some [mostly old, but a little new] footage and a couple interviews from Gamescom so far.
So on that part sukik
will back me up its actually super easy. It's just a wonderful mental fuck the devs do. It is very scary but you can follow a certain path and be done with it pretty soon or at least hit checkpoints. I went through on easy and on hardcore mode and both playthroughs it was the same.
I still haven't finished all of 2033 but I did the gorilla bit a way that I don't think was intended. I just ran through that shit. It took 3 or 4 tries but if you could train our way out of Guk or Sol B then you can do that here.
