I think your facts are a bit mixed up.
You need to download the Bungie app to get a star nameplate, or have someone else give one to you.
Through this app, you can get Blue Flames and a Bungie nameplate, so the guys you killed weren't from Bungie. Sorry... :(
And the Invasion thing is you have to play 5 Invasion games to qualify for a playlist which is comning later.
Why is it all so confusing??!!
