Konami has initiated legal action in a California court after source code and internal development materials for Metal Gear Solid 2: Sons of Liberty were posted online, according to court filings and reporting by Aftermath and Kotaku.
The files, described as containing non-public game assets and internal materials, were circulated on imageboard and file-hosting sites earlier this year.
Metal Gear Solid 2 originally released in 2001 for the PlayStation 2 and has since been widely cited as one of the most influential games of its generation.
The reported leak reportedly included files dated 2007—material that observers have linked to work on the Metal Gear Solid HD Collection—and contained references to an unreleased port of Metal Gear Solid 2: Substance for the Nintendo Wii as well as assets tied to the game’s E3 demonstration and promotional trailers.
In its June 2 court filing, Konami asked the sites that hosted or linked to the materials to preserve any data that could identify those responsible for uploading the content.
In plain terms, Konami told the court it wants to trace the origin of the leak and prevent further public disclosures of its intellectual property.
The publisher also requested that the hosting platforms retain and segregate logs or other records that could help identify the individuals behind the uploads so Konami can pursue legal remedies.
Konami did not name the sites as defendants in the complaint.
Instead, the suit lists anonymous defendants—John or Jane Does—with the aim of using discovery to obtain the identities of the alleged leakers.
According to the filings cited by Aftermath and Kotaku, the company stated that the platforms in question had not produced information that would allow Konami to identify the people who uploaded or otherwise distributed the materials as of the date the lawsuit was filed.
The leak prompted immediate attention from preservationists and modders in the Metal Gear community.
Many users accessed the files to examine scrapped content and earlier builds, while modding teams attempted to restore missing or cut elements from playable builds where possible.
Konami’s legal move follows a broader pattern of rights holders using civil discovery and takedown demands to address unauthorized code and asset disclosure.
As the case proceeds in California, the filings and any subsequent discovery could provide additional detail about the scope and provenance of the leaked Metal Gear Solid 2 materials.
