Package beta keys?

so i was looking around on steams soldier front 2 wiki, i found that there was beta packages people got from aeria games. Fearless scout package, BetaBlasters package, Hero's welcome home package. All these were attained by a speacial key given to you after signing up on aeria games and downloading soldier front 2 i guess. I am wondering if anyone has spare keys they would be nice enough to pm me or email them to me. please and thank you

All package events are finished.
