Want ‘Halo 3′ multiplayer? Do you?

Microsoft announced that next spring, it’s going to put on an open beta test for “Halo 3″ multiplayer in spring of 2007, exclusively on the Xbox 360.

According to the story from GameSpot, Microsoft is planning to air an ad on Dec. 4 during “Monday Night Football” (what, no Super Bowl commercial? boo!).

Meanwhile, “Halo 2,” the first-person crack of choice for current-gen Xbox owners, is getting some new multiplayer maps in the spring, but you’ll only be able to get them if you have a 360.
