The First-Half 2026 Roadmap

The First Descendant has unveiled its roadmap for the first half of 2026, focusing on expanding combat content, improving balance and enhancing the overall farming loop to completely reinvent the core fun of the game. To support these goals, new content updates will roll out monthly, alongside ongoing adjustments to Descendants and weapons.

A first look at what’s ahead for 2026 was revealed during the livestream, showcasing plans to reorganize the cycle from setting goals, to farming and to challenging endgame content. Players also received a first glimpse of new content, including the new Breach Tracking. This opens up a wide gold-farming region where fields and missions rotate randomly, helping reduce repetition. For players seeking high-intensity endgame action, the new Onslaught Mode offers a separate challenge. Parties of four face waves of increasingly powerful enemies, strategically placing turrets and buffs using resources gained during battle.

“Beyond just adding more content, we’re taking community feedback to heart by expending the best elements of the game and reorganizing and rebuilding the core experience to make it more compelling and welcoming for players as the game enters its next phase,” said Minseok Joo, Creative Director of The First Descendant. “As players reenter the world of The First Descendant, we hope they will discover a new vision of the game they knew.”

The new Descendant Dia will also finally make her debut in Season 3 Episode 3, arriving in February 2026, which features a main storyline centered around her. Upcoming plans also include a major overhaul of the farming loop with features such as the Operation Command System and Descendant Mission Dashboard, improvements to the early-game experience including Boost Path 2.0, monthly balance updates for Descendants and weapon reworks, and optimization and service stability enhancements including new performance and optimization settings. The Hard Mode of the Void Intercept Battle will also be renewed into a new endgame content.

Updates Coming to Season 4

Season 4, set to arrive next summer, will explore Karel’s story and the final battle, culminating in the introduction of a new Mega Dungeon designed to match the scale of its narrative. Players can expect missions featuring larger-scale combat and more dramatic presentation than previous Infiltration Operations and Void Vessels.

Season 4 will also introduce a complete overhaul of the weapon system. The current progression structure of research, readjustment, and augmentation cores has become cumbersome for players, and will be renewed with a more streamlined system. Transcendent-tier weapons will be restructured around farming content, with the goal of delivering an entirely new weapon system experience.
