The game was released in Europe in December, but did not sell very well, and wasn't picked up for North American release, with Sony choosing not to publish it themselves. In April 2004, however, Namco announced they had acquired North American distribution rights, with release slated for August. The North American localization was first previewed at the 2004 E3 event in May. For the North American version of the game, over 1,500 fixes and improvements were made, with the grenade targeting system and the camera and combat systems refined. Some of the puzzles were made easier, but combat was made harder. In Japan, the game was released on September 2, 2004, published by Electronic Arts Victor.
