Mind-numbingly exhausting in every way, an absolutely terrible experience. It doesn't try to build upon its predecessors, it's basically the same as the Pre-Sequel with more memorable antagonists. Instead, it's even more sluggish mainly because its story refuses to end, collecting keys to build keys to do something but unfortune strikes and you take a detour, for 30+ hours.

The story is very much superhero-esque, the most important things happen in cutscenes with bewildering consequences and actions that make no sense - the worst death scenes I've ever seen, as well as a shoehorned bittersweet ending with basically no setup. The only good things about it were Lilith and maybe Tina. Everything you expect happens, Claptrap does something dumb in the beginning, people die, people didn't actually die, some new concept about the vaults springs into existence, there's nothing new.

The balancing is once again atrocious, but instead of being under- you're much rather overpowered, ending most boss fights hilariously quickly. It's not helped by the hyperinflation of legendary weapons appearing, every second skag has one, and especially during the last chapter it's not surprising to find at least 20 of those - giving you no time to try them out, much less store them. Even with great power, it's a slug to navigate the last quarter because the levels are overly long filled with the same enemy types over and over and over.

I think this all mainly points to a complete collapse of the direction and management, which is sad to see. There seem to have been big cuts or changes in the story, and there has been no time to fix the numerous glitches, UI and UX issues that are still apparent now, three years later.

Play Borderlands 2 instead.
