Gravity Bone is a 2008 freeware adventure game developed and published by Blendo Games. The game employs a modified version of id Software's Quake II engine and incorporates music from films by director Wong Kar-wai, which were originally performed by Xavier Cugat. Four incarnations of the game were produced during its one-year development; the first featured more common first-person shooter elements than the released version. Subsequent versions shifted in a new direction, with the inclusion of more spy-oriented gameplay. The game was released for Microsoft Windows in August 2008.
Gravity Bone received critical acclaim from video game journalists. It was called "a pleasure to experience" by Charles Onyett from IGN, and received comparisons to games such as Team Fortress 2 and Portal. The game was praised for its cohesive story, atmosphere and its ability to catch the player's interest over a very short time span without feeling rushed or incomplete. It received the "Best Arthouse Game" award in Game Tunnel's Special Awards of 2008. A sequel, Thirty Flights of Loving, was released in 2012.
