Gamers Hold Tight for Halo 3

The final installment of the video game juggernaut Halo hits stores Tuesday, and rabid fans are expected to blow away sales records along with pesky invading aliens. Halo 3 will be released at 12:01 a.m., Reuters reports, with hype and sales receipts expected to rival that of Harry Potter and Spider-Man.

The game, designed for the Xbox 360, is the third in a trilogy in which a character named Master Chief tries to save the world from the evil Covenant. In gamers' vernacular, it's a "first-person shooter." Halo 2 pulled in $125 million in its first day three years ago, and this installment is expected to do better. (More Halo 3 stories.)
