It's hard to imagine, what with its virtually endless stretches of virtual roads, but diehard gamers may have already gotten bored with the new Forza Horizon. If you're among that elite group of gamers, you may be delighted to learn that Turn 10 Studios has released a new upgrade package for its latest title. Adding to the substantial motor-pool built in to Horizon, the December IGN Car Pack includes 7 new cars: the McLaren F1, Ferrari F12 Berlinetta, Aston Martin DBS, Ford F-150 Raptor, Hummer H1, Ford GTX1 and 1971 AMC Javelin-AMX.

The DBS is an odd addition having been replaced by the Vanquish. The Hummer comes in open-top Alpha spec, the Raptor comes in a special Halo livery and the GTX1 is a rare roadster version of the Ford GT. The AMC is a classic piece of American muscle, and the Ferrari and McLaren speak for themselves.

The new cars will be available to download from tomorrow (December 4) for 240 MS points apiece or 400 for the whole package, or as part of the Season Pass, from Xbox Live. The November Bondurant Car Pack included the Lamborghini Gallardo Spyder Performante, Shelby Mustang 1000 and 427 S/C, BMW M3 GTS, '94 Nissan 240SX and Jeep Wrangler Rubicon. The Month One Car Pack included the Ferrari FXX Evoluzione, Gumpert Apollo Enraged, Alfa 8C Spider, Mustang Boss 302, Lamborghini Aventador J and '57 Chevy Bel Air. Expect another six-car Downloadable Content pack every month, with a Rally Expansion Pack due on December 18.
