HAEGIN has released an update for its mobile idle baseball game, '2026 Professional Baseball GO!' (hereinafter 'Professional Baseball GO!'), introducing a 'Cheerleader System' and a new lineup of franchise players.

This patch brings the vibrant culture of stadium cheering into the game, enhancing both visual appeal and strategic depth. Notably, it also strengthens team squads by allowing players to recruit legendary athletes representing each club.

The highlight of the update is undoubtedly the 'Cheerleader System.' Users can hire and assign cheerleaders to their teams to influence the flow of the game. Beyond their visual effects, cheerleaders act as 'Supporters' that boost the overall stats of the team. This feature is expected to provide baseball fans who enjoy casual viewing with the satisfying, nuanced experience typical of management games.

Additionally, 10 new franchise players are joining the mound and the batter's box to bolster team strength. The 10 new franchise cards—Lee Jae-woo (Doosan), Ga Deuk-yeom (Lotte), Kwon Young-ho (Samsung), Seo Yong-bin (LG), Jung Eun-won (Hanwha), Choi Hyoung-woo (KIA), Jung Sang-ho (SK), Kim Kyung-ki (Pacific), Jo Young-hoon (NC), and Shim Jae-min (KT)—offer users deeper deck-building and strategic possibilities.

Furthermore, a new event pass has been introduced to provide daily rewards and support rapid growth. Detailed information about the 'Professional Baseball GO!' update can be found on the official Naver Game Lounge.
