I have an Xbox 360 wireless receiver that plugs into a USB port and connects to any average Xbox 360 controller after being synced.


Majority of newer games such as Fallout New Vegas, Skyrim, and Grand Theft Auto IV will immediately switch to Xbox 360 configuration when they find that my controller is connected (Even the buttons on the menus are changed to little green A's and red B's)


Is Fallout 3 new enough to have this feature? Or will I have to use a 3rd party program to get it to work?

Yes, Fallout 3 supports gamepads.
