I was apart of Flights 1 and 3 in the insider program for Halo: MCC. Although, I was not apart of Flight 2 I thought I would still be rewarded the new Halo Insider nameplate. I was posting on the forums because I believe this could be a problem and I could still be rewarded the nameplate for my participation.
The last time those nameplates could be earned was during a brief 4-hour stress test during the Xbox flight of Reach on the 5th of October.
Those who played 5 multiplayer games during that brief window earned the MCC Insider nameplate, while those who played 12+ earned the Insider Plus nameplate.
So far there hasn’t been any way to earn either nameplate on PC. The only people who have them earned them previously on Xbox.
