I am new to the forum but have played through the game twice and am presently in Mayhem. I play on a laptop, and I will be darned if I can figure out how to switch dual purpose weapon modes (eg: switching from automatic to semi etc. on qualified weapons) Googling explains using the d-pad for consoles and Q for PC, but nothing works for me. What am I doing wrong?
Go to Setting->Controls and check what key (if any) is assigned to this action.
Thanks for your help.
