HAEGIN announced on the 22nd that it has implemented system overhauls and content updates for its mobile idle baseball game, '2026 Pro Baseball GO!', reflecting feedback from its users. This update focused on enhancing the game's quality by prioritizing user opinions collected through various channels, including the official lounge.

The most significant change is the overhaul of the batter roster system, which had received many improvement requests. The flexibility of the Designated Hitter (DH) slot has been increased, allowing players to be placed there without position restrictions, making lineup management much easier. Additionally, a new bench player system has been introduced, allowing users to register up to five batters for more strategic lineup construction.

The skill structure for 'Monster' grade cards, the highest tier, has been fundamentally improved so that stat reduction effects apply regardless of the year. Furthermore, 52 new Monster players spanning from 2005 to 2025 have been added. To address inconveniences regarding the recruitment of players from predecessor clubs like SSG-SK, the pickup recruitment system has been optimized based on group team decks.

New content is also debuting, including 'Guild Breakthrough' for cooperation with guild members and 'Special Training' to further boost team power. Beyond this, the update resolves various minor inconveniences players experienced, such as the introduction of a probability calibration system for player promotions, storage expansion up to 800 slots, and more granular team analysis stats.

A HAEGIN representative stated, "This update is the result of intense deliberation to provide a more satisfying game by carefully reviewing every piece of valuable feedback sent by our fans," adding, "While there is still much to improve, we will continue to listen to our fans and evolve constantly."
