At Bandai Namco's summer showcase event, the publisher unveiled a brand new gameplay trailer showcasing extensive footage of Low and Alone navigating through various levels within The Spiral. The trailer highlights the duo's exploration mechanics, environmental puzzle-solving, and tense encounters with the game's terrifying enemies.

The footage demonstrates the seamless cooperation between the two protagonists, with Low using her bow to trigger distant mechanisms while Alone employs his wrench to break through obstacles and operate machinery. Several new enemy types were teased, including shadowy figures that patrol dimly lit corridors and grotesque creatures that respond to sound.

During the Gamescom showcase, producer Coralie Feniello presented the first in-depth demonstration of the Carnevale level—a festival-themed but deeply twisted area filled with horrifying puppet enemies and terrifying "Resident" creatures. This carnival environment contrasts cheerful decorations with sinister undertones, creating an atmosphere of dread beneath a facade of celebration.

The Carnevale section features intricate stealth mechanics where players must navigate through crowds of animated marionettes and avoid the gaze of the area's primary antagonist. Environmental puzzles involve manipulating carnival machinery—including carousels, ferris wheels, and funhouse mirrors—to progress through the nightmarish attraction. Coralie emphasized that timing and coordination between Low and Alone are crucial, as many sequences require both characters to act simultaneously.

"The Carnevale represents the twisted joy of The Spiral," Feniello explained. "What should be a place of laughter and entertainment has become something deeply unsettling. Players will need to stay in the shadows and work together to survive the festival's dark secrets."

Bandai Namco has released an official demo for Little Nightmares III, allowing players to experience approximately 30 minutes of gameplay set in the eerie Necropolis region. The demo is available across all announced platforms, including PC, PlayStation, Xbox, and Nintendo Switch, with the Nintendo Switch 2 version coming at the console's launch.

The Necropolis demo serves as the game's opening chapter, introducing players to protagonists Low and Alone as they navigate through ancient crypts, crumbling mausoleums, and shadowy catacombs. Players can experience the demo either in online co-op mode with a friend or in single-player mode where an AI companion controls the second character. The AI has been praised for its competent puzzle-solving abilities and responsive behavior during stealth sequences.

The demo showcases core gameplay mechanics including character-specific abilities (Low's bow and Alone's wrench), environmental puzzle-solving, and stealth-based enemy encounters. Players will face their first major threat in the form of the Necropolis's lurking guardian, a towering figure that patrols the cemetery grounds and responds to both sound and light.
