Numerous iterations of the game took place during a two-and-a-half year development cycle, including changes Jensen had demanded to polish the title, some elements being added two months prior to the game's release.
Mnogo ponovnog rada na igri se desilo tokom dve i po godine prozvodnje igre, uključujući i promene koje je Džensen zahtevao da bi usavršio projekat, neki su elementi dodati dva meseca pre puštanja igre u promet.
