Hi, I have bought MW2 and Black Ops 2 for PC, I'm just waiting for the codes to be emailed to me. I really don't like using a mouse and keyboard, so was just wondering if I can use an Xbox 360 controller? As far as I know, MW2 doesn't support it, but Black Ops 2 does. Will an Xbox 360 controller work on MW2, if I use Xpadder?

Also, for MW2 on PC using Xpadder and Black Ops 2 on PC WITHOUT Xpadder will:

An unofficial wired Xbox 360 controller for PC work?
An unofficial wired Xbox 360 controller for Xbox 360 work?
An official wired Xbox 360 controller for Xbox 360 work?
An official wired Xbox 360 controller for PC work?

Thanks.
