HOLY FUCK. lol.
I just went into the delta server. And I got a tutorial for you.
1. Buy VIP (YOU HAVE TO!)
2. Go into delta server
3. Preferably channel 9
4. Go into a room and there will be a room full of VIP's.
5. When you play and finish the game, you will end up with lots of XP.
TRUST me, this works, my friend made his account december 2012 and he's Captain. It's the biggest exploit right now lool. Go try!
