Also Coming Soon...
...Halo 3: ODST-themed Xbox 360 avatar awardables. Lots of folks have been asking us if we’ve been doing work on the Waypoint front or if we're planning on delivering any avatars extras that can be unlocked through the Awards program. Yup, our Visual Design team put together some avatars awardables you’ll be able to snag via some achievements attached to Halo 3: ODST.

While we can’t take any credit for the work that went into powering Halo Waypoint – we didn’t have any direct involvement in its development – we are totally down with creating and delivering some cool stuff to the fans of our titles and Waypoint provides us with an opportunity to work with 343 Industries and Halo Waypoint to offer a nice, retroactive bonus for players who picked up and played Halo 3: ODST.

If you’re a part of the Xbox LIVE Preview Program, you already have access to this new suite of Awards (and all the other stuff that program entails). If not, you won’t have to wait much longer before Waypoint goes live. When that switch gets flipped, here’s the achievements that'll unlock the corresponding new duds:

• Tourist – Black ODST T-shirt
  
• Dark Times – ODST Hoodie
  
• Campaign Complete (Normal) – Rookie’s Helmet
  
• Good Samaritan – ODST Body Armor
  
• Vidmaster Challenge: Endure – Dare Recon Helmet (Female), Recon Helmet (Male)

If you’ve already snagged these particular achievements, you’re good to go. Awardable unlocked.
