[Dark Samurai]

Now, I've been seeing stars on peoples names online, kinda like ranking, one star, two, etc., now my little brother informed me that in order to get stars on your name you would have to go into the missions and get stars there... so far, all *small spoiler* 7 */small spoiler* missions have a two star rating. My little brother and I went online to see if I got any stars... turns out he was very wrong... all that work...

So here is my question, how do I get stars? I see them on only the good people... and I was curious of how many stars I have recieved since you cant see them on your own...

Help me out?
