Microsoft officially announced today Halo Reach, which will be released in 2010. But before then, Xbox 360 owners around the world will have the chance to enter a multiplayer beta. The invitation will be attached to every copy of Halo 3: ODST, in a move that resembles the Halo 3 multiplayer beta invitation included with Crackdown (even though ODST would have sold fine without the beta).
Check out the brand new first teaser-trailer that was released today, which we have posted for your viewing pleasure below:
