The Game Speed component will allow you to change the Time Scale of the game (how fast the character moves, how fast physics happens, etc), as well as the sensitivity of both the Adventure camera and the First person Camera. The attributes avaliable to change are:
Reduce Game Speed
Reduce Camera Sensitivity (Adventure Camera Motor)
Reduce Camera Sensitivity (First Person Camera Motor)
To reset all the attributes back to the defaults, call the Action again and set all sliders to maximum.
The game speed can also be reduced or increased by using the Game Creator Action: General/Time Scale. The Camera Sensitivity settings can also be set for vertical and horizontal by changing the settings in the Camera Motor inspector panel. This Action sets both vertial and horizontal sensitvity settings to the same value.
