Halo 3 gorgeous graphics and realistic environments

Michael Pachter, a video game analyst for Wedbush Morgan Securities, told cnn.com that “Halo 3” could sell close to 3 million copies by Tuesday. Other analysts agree.
“This game could sell between 7 million and 8 million units by the end of the year at pretty much full price,” Pachter said, adding that he thinks about half the 11.6 million global users of the Xbox 360 will eventually purchase the game.
OK, you say, a lot of people are shelling out big bucks for this game, but I still don’t know what it is.
Halo is a trilogy of sci-fi, first-person shooter games that pit humans in a guerilla war against a powerful fellowship of alien races known as the Covenant. It’s set on Earth and ring-shaped worlds called halos. The protagonist is Master Chief Petty Officer Spartan-117, or Master Chief, and his image is so iconic he recently became the first video game character included as a wax figure at Madame Tussauds in Las Vegas. Master Chief leads a team of armor-suited Marines fighting for Earth’s fledgling interstellar empire. In “Halo,” the humans destroyed the Covenant’s outpost. At the end of “Halo 2,” Master Chief and his merry band fought the Covenant as the aliens invaded Earth.
“Halo 3” promises gamers the same gorgeous graphics and realistic environments seen in the first two games, as well as the distinctive soundtrack that alternately soothes and pounds.
