Gearbox has recently put up a video on YouTube from PAX Prime that spends about ten minutes going through a bit of Borderlands: The Pre-Sequel. In the video Nisha is Level 41 and they decide to focus on the Law & Order skill tree. The demo is also a direct continuation of the E3 demo. Prior to the gameplay they also briefly talk about Nisha's Action Skill and her three skill trees, so it's a nice introduction to Nisha herself.
