HAEGIN (CEO Lee Young-il) announced on the 21st that its mobile casual idle baseball game, '2026 Professional Baseball GO!', is rolling out a regular update.

This update introduces the new 'FA Season' card grade, designed to significantly enhance the fun of roster building and strategic diversity. The 'FA Season' cards, featuring star players who successfully transferred as free agents between 2020 and 2025 (such as Yang Eui-ji, Na Sung-bum, Kang Baek-ho, Son Ah-seop, and Kim Hyun-soo), are uniquely characterized by their ability to provide team deck effects for both the player's former and current clubs. This allows users to transcend the limitations of existing lineups and employ more diverse team deck strategies.

The update also brings popular cheerleaders beloved by baseball fans into the game. Doosan Bears' Seo Hyun-sook and kt wiz's Lee Ye-bin have joined the in-game 'Cheerleader' lineup, adding to the enjoyment of team development and providing visual flair.

System improvements have also been implemented to enhance convenience in watching games and managing teams. The real-time text commentary feature has been revamped, allowing users to check the status of not only their own team's games but also other KBO stadium matches at a glance, and a direct button to the broadcast page has been added to the main screen.

Furthermore, seven new uniforms have been added to increase customization options, including five commemorative uniforms such as the KBO 40th Anniversary uniform and the 2025–2026 Dream/Nanum All-Star uniforms, as well as two champion uniforms for the KIA Tigers (2024) and LG Twins (2025).

In addition, growth content has been significantly expanded, including: #1 Opening of the 2020–2025 regular season 'HARD Stage'; #2 Expansion of the division league's highest tier, 'Star 2 League'; and #3 Addition of maximum level (10Lv) for position training and SSS-grade effects.

Meanwhile, to celebrate the update, '2026 Professional Baseball GO!' will host a variety of events throughout August. These include the 'Summer Vacation Exchange Event' where users can earn power-up items by completing missions, a 'Legend Cheerleader Pack' giveaway for Liberation Day, special missions for Baseball Day, and a match prediction event, among other benefits.

More detailed information regarding the '2026 Professional Baseball GO!' update and events can be found on the official Naver Game Lounge.
