Microsoft is shooting for a $155 milllion debut.
The videogame "Halo 3" hits store shelves Sept. 25, and Microsoft is positioning it to be the most successful debut of any entertainment property ever with an extensive multiplatform advertising blitz geared to generate debut grosses topping even the biggest of summer tentpole pics.
In its first 24 hours of release in 2004, the second installment of the sci-fi shooter earned $125 million. That number forced many nongamers to take the vidgame biz seriously for the first time.
With "Halo 3," Microsoft's Xbox unit wants not only to top the 2004 figure but to reach $155 million in a single day -- besting the $151 million opening weekend for "Spider-Man 3," the current record holder for a pic at the box office.
