I think I'll probably be getting this. It has extra programmable buttons on the underside so you don't have to destroy your regular PS3 controller by pushing in on the sticks to sprint or melee someone. I'm terrible with the knife so maybe this will help me.
hmm...so you can change sprint to one of the buttons underneath? tempting. although i have played an entire year of W@W with the same controller and it still works like new. Maybe there isnt as much sprinting in that one since we dont play headquarters as much
