So I received an email titled “Halo Insider MCC Flight Four - Steam Invitation” on February 20th. In said email, it discussed flight times (which had started prior to receiving the email) as well as what is allowed to be streamed / posted and what isn’t allowed, and what are known issues with the current flight test. It also stated that I would receive a steam key to the flight test in a secondary email. I have not received that email yet. I just got another email today titled “Halo Insider - Flight Update & Extension!”, but this email also contained no key to participating.
How long does this second email usually take to go through? I would very much like to participate. I have checked my spam folder, as well as every sub-category in my email such as Primary, Social, Promotions, etc.
