Waypoint Armor Breakdown: In order to unlock armor pieces in Reach related to Waypoint, you must unlock achievements in Halo 3, Halo 3: ODST, and Halo: Reach. I'll give an example. I have all the achievements for both Halo 3 and Halo 3: ODST. When I unlock achievements in Reach that are related to ones found in 3 and ODST according to Waypoint, armor pieces will unlock in Reach much like they did in Halo 3 for completing achievements only it's a little more complicated. Simply get as many achievements as you can in Halo 3 and Halo 3: ODST over the next month (preferably all) and when Halo: Reach comes out, get all achievements in that too. Now visit Halo Waypoint on your Dashboard and access your Halo Career Stats. Halo Waypoint will scan your Halo-related achievements and then award you the appropriate Avatar Awards and Reach armor variants according to your achievement statistics and Milestones. Now this is all Bungie-title Halo games and you're asking what Halo Wars has to do with this. Well, it has nothing to do with it as it was developed by a different studio and is not in any relation to the Reach armor variants or Bungie Halo titles of any kind. However, if you unlock all the Halo Wars achievements (assuming you have unlocked all the Halo 3 and ODST achievements), you will be rewarded with a Blue EVA helmet from Halo 3 for your Avatar.
