Following on from what I replied to on a post, I think it would be great to have some sort of Achievement based Purity Seals for fellow battle brothers to display on their armor as a show of dedication and or skill as a player, a seal that makes other battle brothers think "wow, I want that."


Examples of seals gained could be for:


X amount of Tyranids Killed

X amount of Traitor Legion killed

Hardest difficultly complete

Mastered all classes

All achievements unlocked

Completed all co-op missions with the same friends

Highest wave in horde mode


And so on
