For me, it was just a side quest. And I banged it out in pretty short order.
It's just, when I was looking forward to this, I thought it was going to be almost like an episode. I wanted further info into the story of the world.
This just... put me back into shootin' stuff, but not feeling like I was playing out any real meat in the story.
I did both endings, and they were good... challenging enough, but just not enough to make me pump my fist into the air.
