Microsoft has released a list of the contents of this month for the marketplace, including a mysterious check "Rockstar Pass" for the game LA Noire
at a price of 800 Microsoft Points, available from 17 May, the day of release of the game in the U.S.. It is assumed it is a "channel" from which you can access a special bonus content. We do not know if the game inside the packages will be available a code to unlock the pass for free, as has happened for the latest headlines to counter the market.
We look forward to more information and especially the launch trailer of the game that will be available, as specified by the publisher tomorrow.
