The first thing Mr. Spector told us is that Deux Ex: Invisible War is a complete gameplay evolution over the first game. The first Deus Ex was a masterpiece well worthy of our Editor’s Choice award, but it was a very much a PC game. After that, the development team was presented with the challenge of making this very PC-oriented game into a PlayStation 2 title playable with the Dual Shock controller. From their porting experience, the Deus Ex designers were surprised at how they were able to fit all functions of a keyboard and mouse onto a control pad. Warren explained to us that this paved the way for some of the design decisions made for Deus Ex: Invisible War.
