Borderlands 2 is getting four confirmed slices of DLC as part of the Season Pass, but it has even more planned, Gearbox CEO Randy Pitchford tells Kotaku. We already know about one piece of additional non-Season Pass content, the Mechromancer."We will have other, non-season pass related DLC," Pitchford says. "The additional character (Mechromancer) is one kind of example."We've heard rumblings of themes for future Borderlands 2 DLC: One may be an expansion on the weapons manufacturer Torgue, and another might involve Sand Skiff-like transportation. Pitchford reiterates a vehicle-focused DLC approach."Since we finished the game, we've started with some new ideas that we expect will show up in DLC," Pitchford says. "Some new vehicle types are on-deck – awesome stuff."All of the Season Pass DLC packs will be "big," similar to the third expansion for the original Borderlands, The Secret Armory of General Knoxx. Knoxx raised the level cap, added 30 new enemy types, new weapons, new vehicles and improved the AI."The stuff we're planning and working on for the Campaign DLC Season Pass is big DLC stuff – more like Knoxx," Pitchford says. "We're extremely far along with the first campaign DLC. The second DLC is also in amazing shape. The third DLC is a little farther out and the fourth DLC is just in the pre-concept stages."
