This is just in case others haven't noticed. I barely noticed it. There's a new achievement for those that own the game. It's called "Good Guy Nick" and you're supposed to play in a campaign with free-to-play players from beginning to end.
I just got the achievement and it wasn't easy. I got 3 free-to-play players and they barely had over an hour of gameplay. Even on difficulty set to Easy it was pretty hard because the players didn't know what to do.
Also, just an aside, because of the game being free-to-play there were 30,000 players. Before then the most I would see is 9,000. Pretty cool. Hopefully a good number of them become regulars.
