The G2 notch key triumphed at the ESL Pro League Season 18, displaying its intricate nature.

Complexity swept Cloud9 2-0 and G2 got by Virtus.pro 2-1, sending those opponents into the mid bracket.

Eternal Fire got by 9INE and Team Liquid topped Lynn Vision Gaming, both by 2-0 scores, to initiate mid-bracket play. The losing clubs dropped into the lower bracket.

The $850,000 Counter-Strike: Global Offensive tournament features 32 teams divided into four groups of eight. Group-stage victors advance to the quarterfinals; runners-up advance to the Round of 12 as the high seeds; third-place teams advance to the Round of 16 as the high seeds; and fourth-place teams advance to the Round of 16 as the low seeds.

The group stage is triple elimination with upper, middle and lower brackets. All matches are best-of-three until the grand final, which is best-of-five.

The event runs through Oct. 1. The winner earns $200,000 and qualifies for the 2024 IEM Katowice event and the 2023 BLAST World Final.
