Anyone know what this is? In Jacob's estate next to target of opportunity

I suggest just playing through the game some more :wink:

Well I’ve beaten the game I’m going through on TVHM now and I just came across it. Does it have something to do with a side mission or the vaults?

If you beat the game, you should be able to figure it out, you activate it, follow its quest for some trial challenges.

Gotcha, thanks.
