Microsoft and 343 Studios have announced an invitation-only access to Xbox One Preview members to participate in the Halo 5 Beta. This early access period, which begins on December 19th and ends at 11:59 PM PST December 21st, will only feature content from Week 1 of the Halo 5: Guardians Multiplayer Beta, whereas the full beta will feature a total of 7 maps, 3 game types and a host of weapons that are released across the 3-week period.
/// How to Participate
On the 19th, you’ll receive a message from Xbox Live on your Xbox profile containing 2 codes you need to redeem to get into the early access for the Beta.
The first code allows you to download the Beta to your console, and the second code is a small download that grants you access. You will need to redeem both tokens on your Xbox One console or on Xbox.com to participate in the early access period for the Halo 5: Guardians Multiplayer Beta. Be aware that redeeming one token will not allow you to participate; both are necessary.
Please note that these tokens are intended solely for your personal use as a Preview participant. Any attempt to sell, give away, or trade these tokens will have consequences, up to and including removal from the Preview program and exclusion from future participation.
