Apparently we're halfway through and I have no idea what the hell is going on. It has still never been established why this Handsome Jack guy has it in for me or, really, why he's bad as he seems no more sadistic than the people on your side. He wants to open the vault, which given that we’re vault hunters makes us rivals, but he’s also attacking the flying space town that was put into the air by some magic lady who has special powers for no given reason.
And that vault you’re hunting isn’t a vault, whatever you thought that was going to be, but an alien warrior made out of luminous purple rocks. Also, a video of a person with no specified motivation to help me will occasionally chime in to break the art aesthetic and tell me where to go, much later you learn she's an AI and called Angel but not how she's talking with you and, in a shocking and totally not confusing revelation, that she is and isn’t working for Jack who is the bad guy because he says so.
Just shoot stuff I guess.
