Unmechanical: Extended is an extended version of Unmechanical and it is the first release of the game for the console platforms. The main gameplay is identical to the original game. The player controls a small robot in a 2.5D side-scrolling environment and needs to complete environment based puzzles to progress. This Extended version of the game was created by a new developer and adds an Extended story mode to the game with new levels, along with additional story elements and puzzles, next to the levels of the original version.
For Windows, the Extended version was a free update for the original game, thus replacing the game's default version. Support for Macintosh and Linux was added along with the update.
