Atari and Eden have released a Lexus car pack for the Xbox 360 version of Test Drive Unlimited, featuring the incredibly hot Lexus GS 450h hybrid sports sedan. The pack is free via Xbox Live and also features the Lexus LS 460 luxury sedan model. For those Xbox 360 owners who haven’t yet tried Test Drive Unlimited, I encourage you to give it a try. It’s certainly not the greatest racer of all time, but the persistent atmosphere and recreation of Oahu are more than worth it.

Microsoft’s online service, Xbox Live, announced yesterday that they’ve reached the 4 million subscriber mark, with projections showing more than 6 million by June 2007. Yet still it takes me ±15 minutes to actually get an online Street Fighter match going. Currently, Xbox Live is the largest platform for high-def, on-demand content and pulls a 24% trial-to-purchase rate. Not too shabby, but Microsoft has always led the way with their online service and I seriously doubt Sony or Nintendo will be able to build a better system.

After many rumours, RedOctane finally announced that Guitar Hero II will see a release on the Xbox 360, with the game and the “X-Plorer” controller currently being shown at Microsoft’s X06, currently underway. The controller is designed specifically for the Xbox 360 and players will be able to download new content, such as rock rhythm, lead and bass guitar tracks (awesome).

Microsoft’s Major Nelson announced the new content this week for the Xbox Live Arcade, with no major announcements other than the availability of the Lego Star Wars II demo, which is now available for download. The only other items announced are trailers for titles such as Just Cause, The Darkness, Sonic and several others. I’m totally looking forward to the new Lego Star Wars though, not only because Chewy rips off little Lego arms, but also because I think the original was quite a feat for a Lego-inspired game and certainly a fun little extension of the aging Star Wars brand.

Yes yes I know the high score for Geometry Wars on Xbox Live Arcade is now like, 12312368 billion gazillion, but still, this short video featuring parts of “K4rn4ge’s” 21+ million run is still astounding.
