Have you actually seen an ad for it yet? I’ve seen nothing despite getting the update.
Anyway, Axton resumed main story, this time tackling the pipeline and data stockade. I handily got past Saturn, dinging level 79. It turns out once Saturn has jumped down and been lured to the building, if you drop a turret close enough to one of the end walls Saturn will try to stomp it repeatedly but will be unable to do much damage. Which leaves him a sitting duck for whatever you want to spam at him while he’s preoccupied.
Had a lot of difficulty with the rest of the mission, though, due to shield issues. A had a purple Vladof absorb shield which had decent capacity but not much else going for it. FFYL and death far too many times. Got through eventually and completed the mission, but it was not pretty.
After that, I decided to hit the Golden Chest in search of a better shield, which was successful. Then I did the Highlands Hidden Journals quest by vehicle - got through without firing a shot! Finished with Torture Chairs and a couple of the Monster Mash missions. I’d like to get to level 80 before talking to Clappy and going to Heroes Pass. Got about half-way there so I’ll polish off a few more easy side missions next time.
