Legendary achievement unlocks.

lol I was actually thinking that initially I just thought it might not be popular.

My intinial thought was this.
1. Player meets a requirments listed and gets a special code
2. Player would use the code to get access to an unlock in the game app (Separate thread)

I mean it's worth seeing how other people would receive it but I'd be in favor of that method.
