Hey, I'm about 3 hours in right now and loving it. Of the three, its probably my favorite.
 
I'm dying to know though, what are those friend vouchers?

Finally got around to finishing MP3 (for the first time). Ended up with the following...
 
     Difficulty - Veteran, Percentage Complete 91%, Total Time 20:11
 
I'll be the first to say, 91% was fucking sloppy. And hey, if any of you guys have some friend vouchers (or whatever they're called). I'm ready to trade some.
