If you want Spec Ops: The Line working with your Logitech Rumblepad2 or Dual Action Gamepad, you will have to follow...
Extract the files :
and copy them into folder :
\Program Files (x86)\2K Games\Spec Ops The Line\Binaries\Win32\
If you cannot find the folder, search for SpecOpsTheLine.exe, and place the files in the same folder found.
Don't know much about this game, but I will give it a go, mostly because there is not much else out there at the moment.
