This is from GameSpot "
Well, that "later time" was today. Microsoft confirmed that specially marked boxes of Crackdown will include Halo 3 beta keys. Crackdown will be available in North America on February 20.
The final way to get into the beta test is through the "Rule of Three" program. From February 1-3, gamers in the US who play three hours of Halo 2 over Xbox Live will qualify for entry. The first 13,333 gamers who have played Halo 2 over Xbox Live during the specified time period and who register at the Halo 3 Web site will be entered into the beta program. Gamers outside of the US should stay tuned for details on the "Rule of Three" program in their regions.
Only gamers with an Xbox 360 and a valid Xbox Live Gold membership will be considered for the program."
Ok so I have to buy a game and get a 360 Gold Membership by Feb third and be one of the first people to sign up to play a Demo??? Ummmm sounds like Fame has gotten to Bungie's head. I was going to get the 360 when the Halo 3 demo came out but not know, there's no point becuase I have to play 60 bucks for some game I dont want then maybe if I get luckly get to download a demo??? This is why I hate Mircosoft they take your money from you and even then you might not get the Demo??? That sucks just give us the damn Demo instead of beng asses about the one game that they have and is good. Well thats all i wanted to say.
