CS Nation vient de réaliser une entrevue sur Condition Zero. On nous explique en quoi les cartes de CZ différent de celles de CS.

As you also said, many of the maps are for single player use and therefore have been detailed and modeled many times more than a typical multiplayer map. The geometry itself is more detailed, and we have the luxury of adding many prop models that enhance the visuals of each level. We have also added motion and movement to many of these models.
All this was done without changing the sense of traditional Counter-Strike gameplay. That was the real trick, to not change the feel of the original game. It was not an easy task, either. But we did it, you'll see.
