How do i host an xbox live game on call of duty world at war?

title is self explanitory, i want to know how to host a game in call of duty 5, world at war on xbox live. please comment.

There is no way to guarantee yourself host on an XBOX Live match unless you create a private match. You do that by selecting "Private Match" and inviting friends to join you.

Hmmm... i dont think you can host a multiplayer one... I know about the party system. I know you can host Co-operative campaign and Nacht der untoten.

Message me i need help with either of these.
