Gravity Bone

Gravity Bone is a 2008 adventure game developed and published by Blendo Games. The freeware 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 it 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. It was released for Microsoft Windows in August 2008.
