Undecember's Abyss Gate Update Adds Hardcore Dungeon

Author:Kristen Update:Jan 22,2026
  • Undecember is launching a brand new hardcore dungeon experience.
  • Within the Abyss Gate, you have one life with no second chances.
  • New and returning players can claim growth-boosting items and other rewards.

In hack 'n slash RPGs, and indeed across the genre, there's always a dedicated group of hardcore players. These individuals have perfected their builds and can breeze through standard content. Undecember acknowledges these experts and presents a new challenge: the Abyss Gate, arriving October 12th.

Genuinely hardcore content is somewhat rare on mobile, perhaps due to the platforms' business models. After all, who wants to lose progress (and potentially money) from one mistake? The Abyss Gate is unapologetically hardcore, granting only a single life to overcome its trials.

Naturally, such formidable difficulty comes with equally impressive rewards for those who succeed. Conquering the dungeon unscathed will grant you new Abyss Stones and Gear Slot upgrades.

Inside the Challenge

Abyss Stones come in three varieties: Dawn's Abyss Stone, Destruction Abyss Stone, and Distortion Abyss Stone. The first type boosts the stats of specific gear categories. Destruction enhances the properties of unique gear. Finally, Distortion allows you to alter the mechanics of your existing skills.

Two new skill runes, Wrathful Blow and Toxic Mist, are also being introduced, alongside the Chain of Pain link rune, providing more tools to tackle the dungeon.

The new season also brings plenty of login benefits. You'll receive a Season Promotion Box to speed up your progress, along with various other valuable items and guaranteed gear acquisitions.

The Abyss Gate certainly sounds like a deadly undertaking. For more intense action, consider reading our review of Hitman: World of Assassination.
