The Battle.net World Championship, which will take place later this year, will be the culmination of more than 30 eSports events run by Blizzard and tournament organizers. These events are collectively known as the StarCraft II World Championship Series. 

The goal of the StarCraft II World Championship Series is to identify a true global champion, as players enter and qualify through open tournaments starting at the national level. The National Championships are designed to allow local heroes to rise to the top and be recognized in their country. The top finishers at each National Championship will earn spots at their continental Finals events, which will be an all-out brawl between neighbouring countries to decide who will represent their continent at the Battle.net World Championship.
