The Overwatch World Cup will return this year with more countries, more games, and more live events, Blizzard says.

The World Cup is a community-driven competition between nations, where the skill of a country's top 100 players determines whether it is eligible for the competition.

Blizzard is already tracking the skill ratings of the top 100 players from every country, and on April 25, the 32 countries with the highest average ratings are selected for live regional qualifiers.

Right now, New Zealand is 33rd, and Australia is 13th.

Once the top 32 teams have been determined, things get convoluted: players from those 32 countries vote in three "national committee" representatives from a field of 10 provided by Blizzard, which selects them from the Overwatch esports community.

The three national committee reps are charged with selecting players for their country. So, in other words, players select selectors from a selection provided by Blizzard.

Four live group stage events are slated to take place this winter across Europe, North America, and Asia.

Each group stage event will see eight national teams going head-to-head for a full week, with the top two finishers automatically qualifying for the Overwatch World Cup finals at BlizzCon 2017.

You can watch these scheduled matches online for free, and a limited number of tickets will also be on sale starting in May for those who wish to attend in person.

The Overwatch World Cup debuted last year, with South Korea eventually coming out on top.
