not become disorientating. A first-person roll was implemented at one time, but it was ultimately dropped. Because Perfect Dark Zero was intended to be an Xbox 360 launch title, the last stage of development was very challenging and several features had to be canceled so that the game could meet the launch deadline. The number of players in multiplayer matches had to be reduced from 50 to 32, and a "dataDyne TV" mode that would have allowed players to upload and watch multiplayer matches over Xbox Live was eventually rejected. Final development for the Xbox 360 was very rushed. The order was given to produce the discs five days before the Microsoft certification was complete. Rare later stated they felt very confident they would pass, but it was a significant risk producing 700,000 disks if a bug turned up. According to Botwood, "very few people believed we could make launch, but everything came together in time and it was out there for day one". The actual development of the game took five years overall to complete and spanned three platforms: the GameCube, the Microsoft Xbox and the Xbox 360. Tilston remarked that, throughout the course of development, the team noticed how the video game industry had evolved as computing and graphics power increased, and how earlier games like GoldenEye 007 and Donkey Kong Country where their development costs were minimal could easily be profitable with a few programmers. Tilston also revealed that the team behind Perfect Dark Zero was composed of roughly 25 people for most of the project, which was "ridiculously" small compared to Xbox 360 generation standards where there are 100 or 200 people working on a team. Despite this, Perfect Dark Zero, from a development cost, made four times its money back. Marketing and release Perfect Dark Zero was first hinted at Nintendo Space World in August 2000, where a brief demo showed a 3D real-time render of Joanna Dark. Some reports further suggested the development of the game with Rare applying to trademark the names "After Dark", "Perfect Dark Evolution" and the phrase "Shot in the Dark". At E3 2001, Nintendo advertised the title "Perfect Dark Zero" on a list of upcoming GameCube releases, but the list was quickly removed. In January 2002, it was reported that Perfect Dark Zero was delayed until at least 2004 due to internal team problems at Rare. When Rare was
