Halo Warthog Message

Eligible players will receive codes to download the Warthog via an Xbox Live Message, and codes will begin to be sent out during the week of Sept. 5. In addition, players who have not played an Xbox One Halo game will still have the chance to earn the Warthog
via a special #Forzathon event coming to Forza Horizon 3 in October.

Codes are usually sent out in batches and given that you have played one of the two games (like you mentioned) you should receive or have received a message from Xbox Live.

If you have ever received a message from Xbox Live in the past, it may be worth going through your message list to see if there's an unread message from Xbox Live due to the recent issues surrounding the Xbox Messages on the Xbox One (new messages not appearing
at the top.)

To answer your question properly, there is no specific timeframe for when you will receive a code. Hopefully you'll grab it soon ready for the 27th!

Mister Beep, I never received a warthog code either. I have the Halo Master Chief Collection. No messages, no gifts. Thoughts?

The CST Warthog will be available at launch as a free download for those who have played either Halo 5: Guardians or Halo: the Master Chief Collection. The download codes will be sent out via Xbox Live Message.

That gorgeous Halo Warthog.
