L.A. Noire - Rockstar Pass Trailer

Once purchased, the Rockstar Pass enables gamers to download all the announced DLC for free as it becomes available on the PlayStation Network and Xbox LIVE, which totals four unique cases, two detective suits and a collectible challenge. Xbox 360 Achievements and PlayStation Trophies will be available in each of the four cases.
The Rockstar Pass is a new way to pre-order DLC, giving players access to all seven paid DLC. The Rockstar Pass is available for a limited-time price of $10 or 800 Microsoft Points — a 50% discount compared to purchasing the DLC content individually.
