Xbox Live members can now download the free ‘Launch Pack’ for TDU. In the pack, you’ll find: The Audi RS4 quattro Saloon and the Nissan Skyline GTR R34. This content is available in all Xbox Live regions.
You still need to ‘purchase’ these cars in the game…but after you download ‘em, head to the nearest Audi or Nissan dealer and check them out. The in-game sticker price on the Nissan is 50k and the Audi is 80k.
