During the Microsoft Keynote at TGS earlier, a few new bits about Halo Wars and the Halo 3 expansion were revealed. First up, and something that just annoys me, the Flood will be in Halo Wars. Unless everyone ends up dying in the end, the reveal of the Flood kind of screws with the Halo storyline.

It wasn’t specified if you’ll actually be able to play as the Flood, but don’t be surprised if they are. Halo Wars is still dated for early next year.

Now, on to the Halo 3 campaign expansion. This new trailer, that you can watch above, premiered during the Keynote that continues on from where the last trailer left off at. The expansion is going to be called Halo 3 Recon and is a prologue to the Halo 3 story. You’ll be playing the game through the eyes of an ODST Marine that takes place before the events of Halo 3 and yes, you can has Recon armor.

The trailer shows the ODST soldier hiding from a pack of Brutes after getting out of his drop pod. We see the ODST soldier holding a brand new weapon, which has to mean that new weapons will be a part of the new DLC. The trailer ends with the ODST following a path that's being created by the Superintendent (the A.I.). Halo 3 Recon will be out in Fall of 2009.

I'm actually excited for this campaign expansion and super happy that this is a prologue and not a continuation. How about you? Are you excited?

Game Details

This new chapter in the Halo universe includes the following:

• All-new campaign content: The Halo 3: Recon campaign is an intriguing side story that takes place during the terrifying events leading up to the Master Chief’s return to New Mombasa in Halo 3. Experience the fate of Earth from the brand-new perspective of a special forces ODST (Orbital Drop Shock Trooper), adding a unique outlook and new gameplay elements to the events that unfold in the trilogy’s finale. While the feel of this new chapter greatly resembles that of previous Halo experiences, Halo 3: Recon will require you to employ more elements of stealth and cunning than ever before.
• Prepare to drop: Known for their courage, valor and, at times, insanity, ODSTs are among the fiercest UNSC soldiers, priding themselves on being the first unit deployed into hostile situations. While not as large or supernaturally gifted as their Spartan comrades, these "Hell Jumpers" more than compensate with their ferocious attitudes and unwavering nerve.
• Expanded multiplayer collection:No Halo experience would be complete without groundbreaking multiplayer content, and Halo 3: Recon gives fans more of what they love. With exclusive new maps and expanded Forge options, Xbox LIVE® Gold members will find more multiplayer content than ever before with Halo 3: Recon.
• Ever-growing community options: Enjoy all the great Halo 3 technological innovations, including Saved Films, screenshots, Campaign Scoring, and four-player co-op. All of the new multiplayer maps fully support the Forge editor, offering endless gameplay customization possibilities.
