As the countdown to the Shanghai Major approaches the zero hour, teams and fans alike make final preparations for the start of Group Stage play. Kicking off February 25 at 9:00 AM SGT in Shanghai, each day of the Group Stage will feature four teams battling through a double-elimination bracket. The top two teams will move into the Upper Bracket of the main event while the bottom two teams will settle for seeds in the Lower Bracket.
