As guides in English are at current moment of writing not readily available on Steam, see below steps how to setup splitscreen.


1. Go to: http://serioussam.com/wiki/index.php?title=SS_Classic_Gamepads
2. Download Xbox360Controller.gro from the webpage.
3. Put it into the root of the game installation (besides the other .gro files).

This will result in 4 new configurations appearing in the "Options>Players and Controls>Customize Controls>Load Predefined Settings" menu. :

• 06a-Xbox 360 Controller - 1
  
• 06b-Xbox 360 Controller - 2
  
• 06c-Xbox 360 Controller - 3
  
• 06d-Xbox 360 Controller - 4

Each corresponds to an Xbox360-compatible controller in one slot. If you have only one gamepad, use the controller config #1. If you have two, use #1 and #2, etc.
