1. Is there a method to solve the code the Machine Brains want in Security 2F to turn them off? Yes I know you can just whack it or hack it, but I attempted to choose the route of most difficulty and couldn't figure it out, even using the methodology for the level's turret code.

2. I could never figure out what the "Janitors" terminal under the floor in Grand Station - Crew side wanted, or did. Probably for the Crew-side turrets since they seem isolated from Luxury. I couldn't finagle any codes from Crews (bunch of 5s and 3s on one wall but no luck) and it wasn't in the Star door outside Crews like I hoped.

3. Similarly, is there a way to convert the turrets on the Police Station side of Grand Station (and the one guarding the Train Station side)? Since they didn't convert alongside Police Station.

4. Is it even possible to nonlethal the superbeing Moth-Abomination boss for the Clean Hands achievement? Dr. Green was also making it sound like it was doable. I don't really plan on doing the achievement, but since nonlethal seemed the hardest path for him, I attempted it. I explored all 4 floors in Experiments (floor 3 and 4 I think literally only had 1 depleted battery as loot, very sad), I tried using the terminal to apparently just temporarily remove a healing light source for the guy (the one on floor 3 had no terminal so clearly wasn't a thing), so I figured activating the 4 tesla coils would stun him. It stunned him into little pieces alright. Reloaded and couldn't even just secretly suck the juice out of him, so pieces it was.
Incidentally, does the fully upgraded magnum not hurt it? I shot at it from afar with my magnum and it just didn't care; didn't get alert, and after shooting it 80 times I don't think it was taking damage. Quite the opposite reaction when I used my dinkier normal pistol.

Similarly curious how the Many Machine is done nonlethally, though in that case I just didn't try the obvious valve puzzle since I didn't think it'd die in my 6-some wrench swing surprise attack.

5. They mentioned Janitors are effectively immortal. How did all the other Janitors permanently kick the bucket?

6. Anyone else think that the Cloak is just a better Nightvision that also turns you invisible? Sure you can't see your PHCD menu but that's funnier so it's better. Glad I saved that for last since I figured it would be too busted, but it went beyond my expectations even.
