Well i saw a halo 3 teaser for something not really sure what. Is it a new game or extension to halo 3. Is it for campaign or multiplayer?

Bungie has not released any info on what this is other than that video. Everyone is just speculating right now. I believe the above poster is correct but it has not been confirmed in any way

There will be an extension. It will be for campaign. You will play a different character other then the Arbiter and Spartan 117. It will be a downloadable add-on.
