The campaign is pretty disappointing. Like...it's fine; it's serviceable, but there's hardly any "story" to this campaign. Anybody remember this
story trailer? None of the cutscenes in this trailer appear during the campaign. I don't know if Borderlands had similar trailers prior to it's releases, but there's hardly any story in this campaign. There's also hardly any dialogue from the characters that you play as, "battle chatter" notwithstanding. There's a lot of chatter from mission control, but your characters have nothing to say about the situations they're put in during the campaign. There's very little buildup between missions, story beats just sort of happen. There's no impact to anything. It feels like this campaign was supposed to be much bigger than it is, and that disappoints me.
Just as an aside to this, the campaign is suppose to have different dialogue at points depending on who you play. This probably won't add on to the STORY, per se, but it should help varied play through feels somewhat unique.
I expected this to be a throw-away situation that's slightly deeper than a generic hoard mode, so this doesn't sound too bad. Also, remember they have fully voiced background dialogue segments that you unlock as you clear goals with your characters.
And it sounds like the DLC story segments are suppose to be shorter than those in game? I'd love for them to turn out like Borderlands 1, where the DLC felt like it answered every issue I had with the default SP (underutilization of certain characters, not enough thematic conversations, a few unsolved mysteries answered, self-aware on the games reception, etc.)
I really enjoyed the character-to-character interactions in the Beta, too. Watching Montana freak out over killin' a freakin vampire, hearing characters make jabs at each other... it's very MOBA like in that way, in the best way possible.
I hope to find a kinda Zen with the story missions, that feels similar to running through specific stages in a Beat-em-up. You know the thing like the back of your hand, and the run is pretty easy... but the chance for some variance still keeps it fun, in something of a high-score chasing way.
