Pokémon Legends Z-A Source Code Leak Follows 2024 Teraleak, Nintendo Responds Ahead of Release

Pokémon Legends Z-A has become the latest high-profile target of gaming data leaks, with a substantial collection of files—allegedly including the game's source code, unreleased beta builds, and sensitive development documentation—surfacing online.

This breach closely mirrors the infamous 'Teraleak' of 2024, which saw significant Nintendo and The Pokémon Company intellectual property fall into public hands. First revealed out of Nintendo's celebrated franchise, Pokémon Legends Z-A is poised for global release on October 16, 2025, for both Nintendo Switch and the upcoming Switch 2.

The next-generation hardware is set to deliver gameplay at 60 frames per second, further heightening anticipation among the fanbase.

However, this most recent leak has raised fresh industry concerns surrounding digital security and developer privacy. My Nintendo News reports that an individual, believed to be the same hacker responsible for last year’s Teraleak, has released major assets related to Legends Z-A.

The leak is said to contain the full source code for the anticipated title, two PC beta builds, three Nintendo Switch builds, and an estimated 10GB of internal documentation.

Such internal materials provide an unprecedented glimpse into Pokémon Legends Z-A’s development process and earlier design visions.

Notably, one uncovered detail highlights that complex architectural assets—such as windows and balconies originally created with detailed modeling—had been simplified for the final release to improve performance or fit other production constraints. While fans are naturally curious, industry professionals and the gaming community alike are reminded to practice discretion when discussing or sharing illicitly obtained content.

Those seeking in-depth leaks should tread carefully, as distributing or discussing spoiler-laden material can impact both the player experience and ongoing developer efforts. Nintendo and The Pokémon Company have historically been quick to pursue those involved in such incidents.

Following the 2024 Teraleak—which exposed source code from other Pokémon projects, employee data, and information about canceled games—Nintendo initiated legal action and requested Discord’s assistance in identifying the perpetrator.

These proactive steps underscore the publisher’s unwavering stance in defending its products and intellectual property against unauthorized disclosures. Despite these challenges, both Nintendo and The Pokémon Company remain focused on delivering Pokémon Legends Z-A to fans worldwide.

With its October 2025 launch on the Nintendo Switch and Switch 2, the game stands as a significant release in the Pokémon series, promising a new adventure while reaffirming the continued importance of security and trust in the gaming industry.
