The Missing Link is an impressive and eerie Zelda romhack years in the making

A demon is roaming the land, kidnapping fairies. There’s a village of zombies deep inside the Lost Woods. Link’s friend Saria has transferred her essence into a sword that shoots out soul (laser) beams when you swing it. The Missing Link is a fan game, all right, but from the hour or so I’ve played, it’s a damn good one.

The Missing Link, released in late July, is a romhack for The Legend of Zelda: Ocarina of Time, first released on the Nintendo 64 in 1998. Unlike some romhacks that remix parts of a game but leave the bulk of it intact, this one is a completely new adventure built out of the bones of Ocarina of Time. The textures and menus and so on will be familiar, but the game has its own story and locations completely separate from Ocarina of Time.
