Things You'll Need
Instructions
Place a copy of the Xbox 360 game into the disc tray of each console.
Connect one end of your Ethernet cable to the Ethernet port on the back side of one of your consoles. This port is located beneath the HDMI port, to the right of the A/V cable port.
Connect the other end of the Ethernet cable to the port on the back of your other console.
Turn both consoles on and begin playing the game.
Select the "Multiplayer" option on both games, then select the "System Link" option. Whichever console selects the "System Link" option first will become the host server for the game. You now will be able to play the same game on both consoles.
