The group stage for The International 10 started earlier this morning, kicking off one of the biggest esports tournaments of the year. To mark the beginning of this premier event, Valve very recently revealed the groups for The International, and they are:
Each team will face every team in its group twice, with the top four teams from each group advancing to the winner's bracket at the end of the group stage. The next four will have to fight through the loser's bracket, with the threat of elimination on the line.
