What's happening is, two maps will be played. Both via elimination, but one of the maps will be on an American server, and the second map on a European server.
If it is a draw, then the players will play the same maps again. Until there is a clear winner.
Example:
US wins 1st map.
EU wins 2nd map.
US loses 3rd map.
EU loses 4th map.
US wins 5th map.
EU loses 6th map.
So US win, understand? If not, I'll clarify it a bit better.
