In some pc games today there is no way to make the character you play walk, there is no key to configure in the games control menu otions to press or hold to make the character walk when in gameplay, but you can using a contoller. In GRFS you only have the option of crouching (which looks odd imho) or go prone (which would be mental to play that way). So, imho a controller has its tactical uses, by just gently pressing forward on the default left stick on the gamepad/controller you can tactically move slowly through the levels if you choose to do so, you can't do this on the pc. Zooming in all the time to move tactically does not feel right and looks odd, imho.
Only benefit with controller is just being able to walk slowly.
