The DLC is short, but pretty solid. It doesn’t try to drag things out — it just gives you some extra content without overstaying its welcome. It’s a quick playthrough, but still leaves a good impression. One thing that really stands out is the music — the soundtrack is genuinely great and adds a lot to the atmosphere. It makes certain moments hit harder and feel more intense.

i loved the dlc, a nice continuation of the main games alternate ending. plenty of enemies to fight, the story is nicely written too. Side note: (more of a question) is anyone else mildly weirded out by the fact that Nora is basically presented as what amounts to a horny fridge obsessed with P-3? (i say fridge because that what she looks like to me)
