Some time ago, we had reported that Microsoft wanted beta testers for the forthcoming Halo 3 game. It seems that they do not have enough people to test the Halo 3.
Apparently, they have given an ad for the Crackdown game in a magazine. Nevertheless, what does that have to do with the Halo 3? The answer is that the game comes bundled with an invite that lets the buyer try out the third installment in the Halo series. You can see that in the picture alongside. On the other hand, this could just be a move to sell more copies of Crackdown, as the offer will be for a limited period. The boxes will be specially marked with a note from Microsoft.
