Handler notes

  • Purpose of this handler is to enable 8 player split-screen either on PC or over LAN with different PCs. Using the game's native split-screen you can have 4 players per instance for a total of 8 players between two instancesn

  • Decide the number of instances you wish to launch and assign your gamepads (max 4 per instance) accordingly.

  • Once in game, the last opened instance proceeds to create a custom online game, make sure that everyone has pressed start on their controller prior to creating a custom match. Once the custom game has been setup, press SELECT + X on the first player's gamepad or F2 to connect your instances, alternatively you can alt-tab to the instance you wish to connect and press SHIFT+TAB. This should automatically connect your instances to the custom match lobby.

  • Last but not least, have fun playing this amazing racing game with all your friends and family!
