In Zero Hour, the Generals now fully come into play. Each one has his or her own speciality, and gain new units or changes in accordance to what they're best at. In Single Player, a "Generals Challenge" mode allowa you to pick a General and fight the others 1v1 on their turf - just like Virtua Fighter or Tekken. You can also choose them everywhere else, and have General v General online battles, although the host can disable them to have a "pure" game just like Generals. All the "new toys" are still there, though, so you won't miss out. The images link to the respective in-depth profiles.
