I know the Mechromancer DLC is not included, but is the Mr. Torgue campaign of Carnage included in the Season Pass? Or is it separate like the Mechromancer?
Yes. It is included, along with the already available Captain Scarlett and her Pirate's Booty DLC and two yet unannounced packs.
when you purchase the season pass for 2400 microsoft points, your basically purchasing all 4 dlc's, your paying for 3 and getting one free, otherwise individually its 800 microsoft points for each dlc, which will add to 3200 M points in total.
Just putting it into writing.
Hope it helps some people :-)
