after trying it. its got great lighting effects, in an otherwise pretty damn dark vault that's very easy to get turned around in. there is lots of scrap and ammo.
that said i would hold off for the time being, while its interesting for 45-60 minute dungeon crawl, its a bit buggy to the extent of activating a console meant i permanently lost vats. i thought i was going to have to reload a game hours earlier but someone posted a console command workaround that reactivates vats
Apparently they fixed the vats issue with the latest patch thank goodness
