Over the past month, 50 national teams from around the world put forward their best players to show off their competitive skills in best-of-three online qualifiers. Teams are comprised of six members, who were either picked by a team captain or voted in by Overwatch fans themselves. Many players have made a name for themselves either through casting their games online or already belong to an eSports team and, like a real sporting championship, have been selected to represent their country based on their ability.

The final teams are Australia/New Zealand, Brazil, Canada, Chile, China, Finland, France, Germany, Russia, Singapore, South Korea, Spain, Sweden, Taiwan, Thailand and USA. Team USA is headed by Seagull, who also represents Shaq's NRG eSports group, while Team Benelux has it's very own Harambe. The World Cup will begin on October 29th with a round-robin group stage that opens into elimination finals on November 4th and 5th at Blizzard's annual convention, BlizzCon, in Anaheim.

The World Cup is important for Blizzard to open up Overwatch to fans who haven't yet entered the world of competitive eSports. By grouping the world's best players into national teams, viewers can follow the progress of their country through the competition, exposing them to pro players that they may not have heard of. Blizzard will hope that the tournament will be an on-ramp for casual players, who will maintain that interest in Overwatch's competitive leagues.
