The Halo team is always looking for feedback on their games and services. By joining the Halo Insider program, players can be considered for early access play sessions with in-development Halo games and content. These playtest sessions are called “flights.”
These playtest sessions are invitation-only and have specific goals, which means not everyone can be selected for every flight. To increase your chances for selection, make sure your Halo Insider settings are complete and accurate.
If this all sounds like something you are interested in, then join the Halo Insider program.
