THE KING OF FIGHTERS 2002 UNLIMITED MATCH

The method for boosting wins in this game is mostly the same as the other SNK fighters available on XBLA. There's one minor difference, though. You and a friend can set up a ranked lobby and your friend can quit to give you an easy win. However, you must actually get into the match itself before your friend will be able to exit the match.

A small change from prior titles, but with you only needing 10 wins for this Achievement, you shouldn't be losing too much time over it.
