Halo 2,” a sci-fi action/first-person shooter game, is a full sequel to the best-selling original and will continue the story of the Master Chief, a genetically enhanced supersoldier who is the only man that has successfully defied the Covenant, a coalition of alien races on a murderous march toward Earth. “Halo 2” surpasses its predecessor both in graphical beauty and combat intensity. The Master Chief and his marine allies return to battle the full complement of Covenant forces, as well as new enemies who have not yet revealed themselves. “Halo 2” also expands the Master Chief’s already substantial arsenal with powerful new weapons, many pried from the twitching claws of defeated enemies, as well as more than twice as many drivable vehicles for exploring vast landscapes or speeding into battle. In addition to its epic single-player campaign, “Halo 2” will be playable online through Xbox Live. “Project Gotham Racing 2” returns to city streets with new fully licensed vehicles from major car manufacturers including Ferrari and Porsche. This engaging racing game sequel includes more than 50 vehicles as well as new cities, including Edinburgh, Scotland, and Hong Kong. More ways to earn Kudos will be available, as well as a new rating system, a more accurate way to rank players rather than just by the number of Kudos they have earned. “Project Gotham Racing 2” also enables gamers to play online through the Xbox Live service.
