On August 2, 2018, Atlanta Esports Ventures, a collaboration between Cox Enterprises and Province, Inc, acquired one of the expansion slots in the Overwatch League from Activision Blizzard.

Additionally, the team signed Dusttin "Dogman" Bowerman as a free agent to bolster their support lineup.

[12] In response, the Reign made roster adjustments, including the acquisition of Andrej "Babybay" Francisty from the San Francisco Shock.

[19] However, in the North America play-in tournament, they defeated the Boston Uprising, 3–1, to secure a spot in the season playoffs.

[27] However, they found success in the June Joust, reaching the interregional tournament but ultimately losing in the lower bracket finals to the Shanghai Dragons.

[28] In the Summer Showdown, the Reign once again made it to the interregional tournament but were eliminated in the first round of the lower bracket by the Dallas Fuel.

[40] The Atlanta Reign's 2022 season saw the team rely on rookie talent to strengthen their roster, resulting in a relatively successful campaign.

Notably, Overwatch Contenders standouts Ojee and UltraViolet provided the team with a stable and consistent backline throughout the year.

Additionally, Venom and Speedily, who had showcased strong performances in the Path to Pro scene, made significant contributions in the frontline.

While tank player Gator didn't receive extensive playtime during the season, the Reign predominantly entrusted his counterpart, Hawk, with leadership responsibilities.

In the support role, Atlanta secured the services of Han "ChiYo" Hyeon-seok and Kwon "Fielder" Joon from the Dallas Fuel.
