So I was playing Crysis 2 and hit a random button on my xbox controller and my weapon went into semiautomatic mode. I could not for the life of me figure out what I had done or get it to switch back. Apparently I’m just dumb but it was so frustrating I tried to search google but came up empty.
Turns out later I discovered it was the “under barrel” option and that you can switch firing modes with the left d-pad.
So if anyone out there is as dumb as me, that’s how to get your Scarab out of semi-auto mode.
