LET IT DIE: INFERNO Launches Season 3 with Yotsuyama Castle, New Weapons, and Mastery Switch Feature

GungHo Online Entertainment and Supertrick Games have officially launched the Season 3 update for the roguelite survival action title LET IT DIE: INFERNO as of June 9, 2026.

The new season is scheduled to remain active through September 7, 2026, offering players several months of fresh content and challenges.

A central addition to the update is the Yotsuyama Castle, a shimmering white fortress that has emerged within the Hell Gate area as an ancient armory turned fungal laboratory.

Players must navigate this new map to face the Kurohatsu Garrison, which includes formidable enemies like the Yotsuyama General and the half-dead Heavy Sentry soldiers.

The Gomamusha boss awaits at the heart of the castle, described as a monstrosity capable of explosive speed and powerful jumps fueled by a fungal propulsion device.

To combat these threats, three new weapons have been added, including the crowd-controlling Metal Whip and the high-risk Plasma Laser that increases in power the longer it is charged.

The Executioner scythe provides players with a long-range option that can chain attacks and fire cursed energy to pierce through multiple enemies.

Two new character bodies named Joe and Inva are now available, with Joe being earned through the Raiders Fund and Inva being unlocked by defeating the boss Dreamseeker.

New armor options include the stamina-focused Signalcade and Strong Plated sets, while the Kurohatsu Armor provides a boost to Deathblow attack power.

The update introduces the Raiders Fund, a community-driven system where players donate Kill Coins to earn personal rewards and reach collective world goals for special unlocks.

Gameplay flexibility has been enhanced with the Mastery Switch feature, allowing all previous bodies to alternate between two different Mastery types for unique builds.

Players can now customize their experience with background music selection, featuring eleven added tracks from the title DEATHVERSE: LET IT DIE.

The River of Souls Clear Event is also currently underway, granting participants the Raider Medal: 2nd Era charm and unique colors for starting bodies.

LET IT DIE: INFERNO continues to support its player base on PlayStation 5 and PC via Steam following its original launch on December 3, 2025.
