in my dream, i'd just gotten to the end of the game, where carmen lures you and chase to her hideout and then separates you (which i now realize was borne from a scene in tales from the borderlands that i played night before last) and then you fight her and a bunch of henchpeople in the final boss battle. it started off with having to fend her off long enough to solve a puzzle, and then getting in her mecha and using it to get to her control room, where you had to alternate between solving number puzzles (it was something like decoding numbers written in base-4 and base-8 to base-10) and fighting villains, and you had to close the elevator door behind every villain or more would come in and interrupt you from solving the puzzle.
