The cog things under the thumbsticks adjust the tension of them. The extra buttons are mappable so that means you can melee on tactical easily or reload without taking your thumb off the stick. I am a bit of a peripherals guy so I am really excited by this.
ah right, mappable buttons. knife + crouch would be the only advantage i can see myself using... might be worth it

dont see the point in the extra/less tension but im stupid
