ULTIMATE MARVEL VS CAPCOM 3

Ranked, Player, Lobby, and Heroes and Herald's mode all count towards this, really easy to do. Also helps to run sets of "friendly matches" with friends!

Straight Forward. Play 300 matches on Xbox Live (Player or Ranked) over time. Win or lose, still counts. If you need to boost, just go into a match and do nothing, let your opponent kill you.

NOTE: Hit RB on the main menu of the game to see your License. Here you can track your progress.
