Major League Baseball 2K9

if you can find someone that has the cards that you need, you can play a ranked card game together. as long as you accomplish the goals for each specific player whos card you are going for they will unlock for you at the end of the game the exact same way they would if you got them in a single player game. and if you have someone helping you out it will be way easier to do the tasks to unlock all of the players that you need.
