At the main menu, select "Options", then choose the "Keyboard/Mouse" selection. Enable the "Allow Developers Console" option. While playing the game, press ~ to display the console window. Type "Exec 360controller.cfg" and press [Enter], then set your split screen mode with the following console codes: "ss_splitmode 1" ("Horizontal-Cut" for standard monitors) or "ss_splitmode 2" ("Vertical-Cut" for widescreen monitors). Connect to a server. Join the server with the "connect [IP address] 2" console code. You must now set the Xbox 360 controller to player two (with the light on the Xbox logo pointing to "2"). To do this, quickly unplug and reinsert the Xbox 360 controller while the game is running. You can now play in Co-op mode in split-screen.
