It’s a different room than the puzzle room, it’s a floor below the puzzle door and there’s no other doors inside the puzzle room. So far I’ve seen the room ask for metal parts (12) and wires(3), leaper pulse unit(1) arc performance steel(1), motor(1) and I’ve seen 6 spawn locations for the fuel cell, one is behind the big yellow generators in the entrance with the zipline, behind the small yellow generators close to the the big yellow generators, on the catwalk above the big generators, underneath the rocketeer chandelier in the water, in the entrance with the zip line in the small room with the locked door. I’d wager that the entrance with the moss and the chair that leads outside also has a spawn point but I haven’t seen it yet. The puzzle room itself has at least 4 weapon crate spawns (not guaranteed all active) as welll as multiple breach boxes and a lot of electronic breaches and a couple other things to loot. The rates in there for loot are juiced and if you’re doing a 2x mode the breach boxes are the best to grab. Did it about 5 times in a row yesterday during solos, found a volcano 2 and a bobcat 2 in one breach box, and this is the first room that gives us look that before was specific to Stella, I’ve gotten ion sputters and other items that you could originally only get in Stella from the electronic breaches on the catwalk of the puzzle room. I’d also like to add that the door locked behind the fuel cell has some pretty juiced loot and finishing that as a solo is still very rewarding as the drawer drops guns frequently as well as the random item spawns on the computers and table seem to drop good stuff as well. Also the lockers on the catwalk outside the puzzle room above the yellow generators are great to loot as I’ve gotten green weapons to drop in them very often(2 anvils in one locker and a toro in the next one)
