LINE Games Launches New Season 'New Age' for Hack-and-Slash RPG UNDECEMBER!

2026-01-15 17:00

  January 15, 2026 – Seoul, South Korea – LINE Games has updated new season New Age for the multi-platform hack-and-slash action RPG UNDECEMBER, developed by NEEDS Games and serviced by LINE Games.   The core of the new season New Age lies in the largest balance overhaul in the game’s update history, affecting more than 100 skill and link runes. Overall skill performance and synergy structures have been entirely revamped, bringing sweeping changes to the combat dynamics and delivering a more advanced and refined UNDECEMBER gameplay experience for players.   Through this balance update, previously underutilized skills and builds have gained renewed competitiveness. Moving away from gameplay centered on a small number of dominant builds, players can now enjoy higher-level combat that leverages a wider variety of combinations and strategies.   The game’s growth systems have also been improved in this update. New special materials have been added that can nearly double the Essence drop rate compared to before, and for a limited time, the existing Darkness Energy can be replaced and used as these special materials. In addition, system changes have been implemented so that Darkness Energy is no longer required when entering the Chaos Dungeon. This update creates an environment where players can freely enjoy unrestricted gameplay even in high-tier content in Chaos Dungeon’s Hard Difficulty.   New rewards have been added to Abyss Gate, the endgame content of UNDECEMBER, for first-time clears at each stage. This provides players targeting high-difficulty content with new motivations for growth and additional challenges.   The Abyss Stone system introduced in the previous season has also been further enhanced. With the conditions for Slot Unlocking eased, more players can now actively utilize Abyss Stones as part of their builds.   To commemorate the launch of the new season New Age and the game's 4th anniversary, a variety of generous rewards have been prepared. Through the 4th Anniversary Exchange Shop, players can obtain powerful Unique Gear and newly added costumes. Additionally, all players who log in through the 4th Anniversary Attendance event will receive the new pet 'Observer'.   Detailed information about the UNDECEMBER's new season 'New Age', as well as game events, can be found on the official UNDECEMBER page and the Steam page. <END>   ■ UNDECEMBER Related Links - Official Website: https://ud.floor.line.games/kr/main - STEAM: https://store.steampowered.com/app/1549250/UNDECEMBER/ - Official YouTube: https://www.youtube.com/c/UNDECEMBER_official
