 God of War : Betrayal was announced by Sony Online Entertainment at a press conference in Los Angeles in May 2007 . The game utilizes a total of 110 different animations and features a 2D rendition of the series ' three dimensional ( 3D ) graphics . The character art and animation were done by WayForward Technologies . The only audio components are an orchestral score in the main menu and background sounds ( e.g. , clashing weapons ) . In August 2007 , Phil Cohen , producer , designer , and game director for Betrayal , spoke of the difficulties in developing a God of War game for a mobile device . Cohen said that although enjoyable , the greatest challenge was creating a single tileset and palette swapping scheme that was diverse enough to portray multiple environments with only several hundred kilobytes , and that met series creator Santa Monica Studio 's high standards . He wrote the initial design document between September and October 2005 , and revisited it in August 2006 , the month development started . The versions for high @-@ end handsets were completed in April 2007 , with final versions for low @-@ end handsets completed by June 2007 . The porting team adapted the game to over 200 handsets in a matter of weeks .
