Quickmatch

Quickmatch is an option for Halo 2 on Xbox Live that quickly connects you to any game available to you from the most recent matchmaking playlist you selected. You have no control over the game type when you select this option, however, it is often a faster connection option.

It is also like Slayer or Team slayer but a never know if you will get it. So its good if you can't think of one to play.
