After running through details of Halo: ODST at their E3 press conference, Microsoft played a teaser trailer for another new Halo game - Halo: Reach, being developed by Bungie.

The trailer shows the planet where Spartans are trained, called Reach, being attacked with plasma weapons or "glassed", by the Covenant.

Bungie also announced that players who purchase Halo: ODST will be given access to a multiplayer beta of Halo: Reach on Xbox Live.
