  May 14, 2026 – Seoul, South Korea – LINE Games has launched new season The Forge for the multi-platform hack-and-slash action RPG UNDECEMBER, developed by NEEDS Games and serviced by LINE Games.   This season, The Forge, brings a significant upgrade to the gear crafting system. The newly added 'Tier 15 Gear Options' offer performance on par with existing Unique Gear, letting players experience the joy of crafting powerful and highly personalized equipment. Additionally, when playing in Season Mode, even higher-tier versions of these options will become available.   A new growth content feature, the 'Card System,' has also been introduced with this update. Players can equip cards featuring unique illustrations obtained through gameplay to enhance their character's Stats. Beyond collecting and upgrading cards, additional bonus Stats are granted based on strategic Deck combinations and Card Album completion progress, delivering the dual enjoyment of collection and character growth.   Two new Skills have also been added to expand the variety of combat build combinations. The new skills are 'Frost Storm,' which creates a chilled area, and 'Axe Throw,' which changes form depending on weapon type, offering diverse action and a strategic combat experience tailored to the battlefield.   A system overhaul has also been carried out to improve gameplay convenience. The end-game content Abyss Gate has received a stage expansion and difficulty balance adjustments. Moreover, the additions of Zodiac Preset Saving and a dedicated Chaos Rune Enchant further enhance the progression experience for more gratifying and comfortable gameplay.   Further updates include raising the maximum Avatar level to 140 and improving the reward criteria for Raid content, with adjustments made across the board. The increase of the maximum Friendship level in the Black Market, the addition of new items, and an overhaul of the Treasure Chest system have also significantly raised the overall reward experience players can feel in-game.   LINE Games will be holding a series of limited celebratory events to mark this new season The Forge update. First, all players who log into the game will receive 100% instant delivery of growth items, including the 'Zodiac Sprinter.' Players can also obtain the new pet 'Sirius' and new attachments through the '7-Day Attendance' event and by completing in-game challenges.   Finally, the Season Promotion Box offers a chance to select new Transcendent Unique Gear, and the Celebration Exchange Shop allows players to obtain powerful Unique Gear and new Costumes.   Detailed information about UNDECEMBER's new season The Forge, 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

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
