So, I legit bought this game due to the hype and intrigue built up by that youtube video.
Now, after beating the DLC, all I can say is, what a fucking snake oil salesman.
The main story is vastly more interesting than the DLC, the DLC is so straight forward its laughable. You go, get the thing either give it to the people who want it as planned, or sell/give it to a faction you like. No big set piece or anything.
*SPOILERS*
Its literally just a warhammer 40k STC, that's it. Being a pretty big lore nerd for 40k this was such a let down. Compared to the faceless, and trchort. A simple STC clone was meh. Not to mention the giant serpent is never shown, and the shadowlith was so underwhelming it literally only messes with you in that single room. Maybe if that shadowlith had say made you rush out of the station, then perhaps cause the giant serpent to go crazy requiring some multistage boss fight. That would have been epic. But nah, it was just a LOST level cloud monster that chases you out of a room cause you stole some warhammer 40k fan fiction. I feel straight up hoodwinked not gana lie.
I was REALLY expecting the giant serpent to have an "occulus" type moment with how the sub is all black screen, expecting it to reveal the scale of the serpent by unveiling it in a similar way occulus did in the main game. It felt so set up to do that but nah.
