Haegin announced on the 14th that the regular update for 2026 Pro Baseball GO will introduce post-season related events and a collaboration with 'Jamsil The Last Inning'. Alongside this update, the game welcomes a cooperative event tied to the Jamsil Baseball Stadium farewell legend game 'Jamsil The Last Inning', scheduled to take place on November 14.

With this update, you can choose professional baseball legends participating in the legend game, complete missions, and earn rewards. Completing missions allows you to acquire player recruitment tickets and prize entry tickets. In particular, if you participate in the first prize entry event running until 9:00 AM on November 5, tickets to watch the 'Jamsil The Last Inning' match will be given through a lucky draw among participants. In addition, special prizes such as a legend team selection box and breakthrough cores are scheduled to be provided.

To celebrate the autumn baseball season, various events will unfold throughout the post-season period. You can participate in a match prediction event to forecast the winning team through fan club content, and acquire diverse rewards through the 'Post-season Board Game' event where you roll dice to receive multiple rewards.

Meanwhile, Haegin has additionally opened a new server in response to a steady increase in users. This aims to support new users so they can compete under the same conditions as existing users. In addition, several contents such as player management, uniform systems, hot time events, and item exchange shops will be improved to enhance user convenience and strengthen gameplay immersion.
