XBox is closing down the 360 store tomorrow so I was wonderring especially as it exposes Dex's change and why. I thought this was suppose to be 360 exclusive so if anyone can clarify that would be helpful.

I own it on GOG & Steam and there's nothing about DLC on either store or in game that I've seen.

Just yesterday, I completed these missions, but they have a warning that cut-scenes and dialogue are missing. I had to look up on YouTube to understand what I was doing.

Edit: Granted, they're probably courtesy of the Gentlemen of the Row mod, very advisable.
