Before I say anything, I want to stress that I love the fuck out of the Borderlands franchise. It just has this charm to it that I always come back to. And I love Borderlands 2 and the Pre-Sequel the most.
And now, it is time to delve into the realm of the However. The But. The nitpicks. Or should I say nitpick, as I only have the one?
If you have not played BL2, play it now, or at least listen to a story breakdown on YouTube, because hell if I'm explaining it.
Firstly, some basics. Hyperion New-U stations are the in-lore respawn mechanic. you die, Hyperion takes your life savings, the station spits you back out. Some stations also function as fast travel. Characters actually use this function in the Pre-Sequel, thus cementing the New-U stations as an in-lore presence.
All of that shatters in Control Core Angel.
Roland gets shot in the back by Jack and dies. Permanently.
Now, this is a game where pretty much EVERYTHING comes back to life with but a save-quit. Even most bosses, as illogical as it is, resurrect by this process.
Roland's just fucking dead, though, and this makes no sense from a gameplay perspective. From a lore perspective, it's fine. Jack is letting you know he's not fucking around anymore. You JUST killed his daughter.
But in terms of gameplay? We played as Roland in BL1. He had to have interacted with at least ONE New-U Station. And if Jack somehow blocked him from accessing them, why the hell can we still use them, even AFTER this point?
Even still, Borderlands has a system in place where you cannot get killed in one shot when you're above half health. Roland shouldn't have died in the first place.
But let's just say that he was under that threshold and that Jack DID stop him from respawning. Jack himself dies at the end, and while one of the problems is no longer, the OTHER has become a wall.
We see Jack interact with New-U stations in the Pre-Sequel, and no self-respecting megalomaniac takes down the only thing barring him from a permanent death.
IN CONCLUSION, neither of the deaths in BL2 should have been possible.
