i got invited to the season 8 flight. i added the steam product properly. i downloaded the “halo: master chief collection - insider” and now i dont see anything saying anything about halo infinite. when i check out campaign it just gives me the option to play: reach, halo 1, and halo 3. same goes for multi player. am i just big dummy or is there actually something missing here?
No, this is what you should expect as they’re only testing for those specific games, with specific levels included.
If you read through the overview of the Flight & the Known Issues threads on the Halo Insider Support page, it goes into more detail there. 
i suppose it was being big dummy. i appreciate the help .
This particular flight is testing MCC Season 8 content, not Infinite. Hopefully there will be another flight for Infinite before December rolls around.
is there even a halo infinite beta thing in this flighting, because i really dont wany my invitation to be wasted
-edit: i hadn’t refreshed the feed so i didnt see what you said
