Hello all, I would love to have the bungie callsign next to my name… can you all help me?

You have to link your account to the bungie.net website but right now because bungie is over for halo I don’t think you can do it anymore

Lol te bungie call sign one is the most common, assault rifle or battle rifle or even the “HALO” ones are the rarest.
