The Legend of Zelda: Book of Mudora

The Legend of Zelda: Book of Mudora is a fan-made action-RPG built on the Solarus engine by developer Matt Wright, first released in August 2017 and still receiving updates — most recently in mid-2026, running on the newer Solarus 2.0.0 engine after starting out on an older version. Set generations after Twilight Princess, it follows a Link-style hero racing to stop the Dark Tribe from destroying Hyrule by claiming the power of the Book of Mudora, a mission that spans two separate continents within the kingdom rather than a single unified map.

Structurally, it's built the way an official 2D Zelda game is built: eight distinct temples anchor the campaign, each with its own puzzles, items, and boss, alongside an overworld sized to match — not a short tribute level or two, but a genuine full-length adventure. Progress follows the familiar Zelda loop of finding a dungeon item, using it to solve that dungeon's puzzles and beat its boss, then carrying the new tool back into the overworld to reach areas that were previously blocked. Along the way, the story has the hero helping several of Hyrule's other races work through their own conflicts, which gives the two-continent setting more texture than eight dungeons run back-to-back with nothing else between them.

What stands out is the timeline. Book of Mudora has been in active development for close to a decade, moving from its 2017 debut through a full engine upgrade to Solarus 2.0.0 and up to version 1.5, adding all-ages content, multiple language options, and configurable controls along the way. That's a maintenance commitment most free fan projects — and plenty of commercial ones — don't sustain, and it shows in how complete the finished structure feels rather than how ambitious the original pitch sounded.

PlayBound lists it because a solo developer sustaining a full eight-temple Zelda-style campaign for the better part of a decade, entirely for free, on an open-source engine, is exactly the kind of long-haul independent work that's easy to miss without a catalog actively surfacing it. It's not a tech demo or a weekend project — it's a complete game that happens to cost nothing and answer to no publisher.
