Tunic is an action-adventure game by Andrew Shouldice and published by Finji. The game was released in March 2022 on macOS, Windows, Xbox One, and Xbox Series X/S, which was followed by ports on the Nintendo Switch, PlayStation 4 and PlayStation 5 in September of the same year.

Tunic (originally named Secret Legend) was developed by Andrew Shouldice. Shouldice was a developer at Silverback Productions for about six years, and in 2015, having participated in a few Ludum Dare events, he wondered what he could produce if he worked full-time on Tunic rather than just on weekends. He considered the state of his own career at Silverback and decided to quit to pursue this development.

Shouldice stated the game was inspired by "certain classic triangle-seeking games," obliquely referring to The Legend of Zelda series. Within the game, the player finds pages of instruction manuals, the art which was heavily inspired by the instruction booklets for the Nintendo Entertainment System games The Legend of Zelda and Zelda II: The Adventure of Link.  As he started working on the game, he gained interest from Finji, Adam Saltsman's publishing label. Finji offered to publish and help refine the game, taking some of the experience they had in preparing Moss for the PlayStation VR release. The game's soundtrack was composed by Lifeformed, who previously composed music for the 2012 game Dustforce, and Janice Kwan.

At the Electronic Entertainment Expo 2017's PC Gaming Show, the game, previously developed as Secret Legend, was renamed Tunic, along with Shouldice's collaboration with Finji to help publish it. The game was subsequently featured during Microsoft's presentation at E3 2018, where it was announced as a console launch exclusive to the Xbox One, alongside its planned release for Windows.

Tunic launched on March 16, 2022. In addition to macOS, Windows, and Xbox console releases, it also was added to Xbox Game Pass the same day

Tunic is played nominally in an isometric view, allowing the player to maneuver their character, an anthropomorphic fox, around the game's world, interacting with objects and fighting enemies; if necessary, the player can switch to a more top-down view in combat. The game is structured similarly to The Legend of Zelda, with progress limited to certain areas of the game world until the player has collected a new weapon or ability for the fox to use, adding some touches from the Dark Souls series. The game's purpose and method of playing are somewhat oblique; what dialog is presented to the player is generally of a strange language, though selected characters or words will be legible in the player's language that may hint towards puzzle solutions, and some of the items that the player will find are pages that make up the game's manual.
