I've never played FPS games on consoles. I borrowed MW2 from a friend and ran through the campaign. It was a great game so I just bought Black Ops. I used to own quake 3, rogue spear, etc. back in the day. The change over from keyboard to gamepad is not so easy. I know I can buy a keyboard, but I'm assuming the top players learned on a gamepad.
Any advice on gamepad sensitivity, button configurations and/or gameplay suggestions is much appreciated. I'm getting pwned in multiplayer, but only rank 8-9, after playing last night for a few hours.
