How do you change mouse sensitivity in FPS template?

Just need to change the mouse sensitivity when I hit play in FPS template game. Don’t need a widget or anything to change it in game just need it to be slower from the beginning as its for a virtual tour. Can’t seem to find an answer anywhere.

Any help would be awesome.

Hi, just multiply the Mouse input with a float value of something below 1 to slower it. (0.5 for example for half the speed)
