Though on the door, I could have sworn I scanned both of those things.
WRONG!!! FALSE MEMORY YOU FLAILING BABOON!!!!!
So, as far as I got, my only additional thoughts are, maybe put the pulse on X and Scan on S. X is in a more comfortable resting position, the EMP requires more reflexive use, and I used it a lot more often than scan.
(Also S stands for Scan. So it all really works out.)
Sorry I didn't play further, but the bugs were really wearing me down.
Maybe the game just doesn't get on with my computer.
