The Microsoft Xbox 360 console supports system link, which allows you to connect two or more Xbox 360 consoles together to allow players to play the same game on separate television screens. Setting up system link on multiple Xbox 360 consoles is straightforward process. All you really need is one system link cable, if you are connecting two Xbox 360 consoles together and no internet connection is required. If you are connecting three or more Xbox 360 consoles together, then you will need more system link cables. You will be requiring them to connect them into the Ethernet ports of the consoles and the router, making the system link connection active.

Popular games like Call of Duty Black Ops 2, Blur, Halo 4, F1 2012, Project Gotham Racing 4 and Bioshock 2 all support system link. Usually, if you look on the back of the DVD cover, it will say if the game supports system link or not.
