Instructions
Connect two controllers to your Nintendo GameCube or Nintendo Wii game console. If you own a Nintendo Wii you can also play the game on that console, even though the game was designed for a previous Nintendo console.
Insert your "Buffy the Vampire Slayer: Chaos Bleeds" game disc into your Nintendo GameCube.
Select the icon for the game from the Wii main menu (for Nintendo Wii users only).
Select "Mulitplayer" from the "Chaos Bleeds" main menu.
Select the game play mode and mission you want to play from the menu on screen. With both controllers connected and all selections made, the multiplayer mode will begin on your TV.
