The side missions that you find in Torgue’s Campaign of Carnage change things up a little from previous Borderlands 2 DLC campaigns. A number of the missions are battles divided into tiers where you fight through the first tier during the story missions, but then return to play through 2 more additional tiers at higher difficulties. You can also replay the three different types of battles by choosing “rematch” missions from the battle boards outside each of the areas. These rematches don’t count towards completing all of the side missions however. Some friendly faces make their return throughout the campaign and the side missions let you interact with them a little more than you would normally. Also, you’ll snag yourself the “Motorhead” Achievement/Trophy for completing them all as an added bonus.
