Whoa, awesome! It’s so much nicer to play with a 360 controller~ Thanks for the update!
What’s the auxillary action about?
It depends on the weapon you have equipped. For some it guards, on Gunslash it changes attack mode and for others it changes between attacks you have equipped to the weapon.
Nice! Thanks.
Does this work with a PS3 controller too? if so how do i get my analog to work?
