I'm talking about the shock of course.
I turned the hints on and that didn't help, spent 5 hours in the end trying every item combination possible everywhere. It just seemed like bad design, not because you can't cheese it by trying random combinations (that's a good thing) but because it seemed so completely.. random. There's also the red herring of DeSinge's shock pedal, which seems way more logical than a shock by the door that doesn't seem connected to anything at first.
The rest of the game was great though. Best episode yet:D
