I started playing the Emulations scenario today, but now I can't figure out what to do next. I'm at the point where I have to disable the crystal controlling the gargoyles, but I 'm not sure how to do that. I thought it had to do with placing the silvered crystals so that the silvering beam reflects off of them and hits either the gargoyle control crystal or the energy crystal in the next room, but this isn't working for me, and I can't think of any other solution. Could someone please help me?
