I-Ninja sequel footage surfaces: 20 seconds of Argonaut Games prototype revealed

Argonaut Games' cult-era action platformer I-Ninja, first released in 2003, has re-emerged in the headlines after a short piece of prototype footage for a cancelled sequel was made public.

The clip — released to preservation group Games That Weren't by an anonymous donor — runs roughly 20 seconds and shows an underground cavern environment from the unreleased build.

I-Ninja was developed by Argonaut Games and released in 2003; the studio later shut down in 2004.

The newly surfaced footage gives a rare, concrete glimpse into development work that was underway before the studio closed its doors.

Games That Weren't published the clip to its archival channels, describing it as a "previously unseen" segment of the cancelled project and noting its provenance from a private donor.

The short sequence displays level geometry, lighting and camera work that indicate active production progress on the sequel prior to Argonaut's 2004 closure.

In journalistic terms: preservationists confirmed the clip exists and shows an underground cavern stage, providing evidence that the project had moved beyond conceptual stages into in-engine level construction.

Fans of Argonaut's back catalogue have renewed interest in legacy properties such as Buck Bumble and Croc following recent community attention on remasters and archival releases.

Argonaut's I-Ninja built a modest cult following since its 2003 release, and the resurfaced footage has prompted archival groups and longtime fans to re-examine the studio's unreleased work.

At present, there is no official confirmation from Argonaut or rights holders about a broader release of the prototype footage, a downloadable build, or an official remaster of the original I-Ninja.

Preservation organizations like Games That Weren't routinely publish short clips and documentation to support research into cancelled and unreleased titles.

What is verifiable: I-Ninja is a 2003 title developed by Argonaut Games; Argonaut ceased operations in 2004; Games That Weren't publicly shared a 20-second clip from a donor showing an underground cavern from a cancelled I-Ninja sequel.

For readers following classic-platformer revivals and potential remasters, archival releases like this are a primary source for understanding mid-development work.

Watch lists and storefronts such as Nintendo eShop and platforms like Nintendo Switch continue to be places where remasters of older franchises often appear, should rights holders choose to pursue official re-releases.
