The Esports Championship Series (ECS) has revealed the groups for the upcoming season 4 finals.

Running from December 15-17 at the Hard Rock Hotel in Cancun, Mexico, the event will feature the top four teams of the European and the North American divisions, who will pit their wits against each other for the lion's share of a $750,000 prize pool.

Both groups feature the first and third seeds from one region and the second and fourth seeds from the other, which resulted in a mouth-watering Group B that features Cloud9, Liquid, FaZe and Astralis - the four highest ranked teams in attendance.

The group stage, which will presumably feature a double-elimination format, with best of-three elimination and decider matches, will lead into a single-elimination bracket with the top two teams from both groups.
