As of last night at 3am EST, the new Xbox 360-exclusice DLC for GTA IV has landed on the Xbox Live Marketplace. This DLC pack brings us a whole new set of missions, dealing particularly with biker gangs, but we still play as our dear Niko Bellic.

Johnny is a veteran member of The Lost, a notorious biker gang. Johnny has been creating business opportunities for The Lost in Liberty City, but his first loyalty must be to the patch he wears on his back and to Billy Grey, the club’s President. However, when Billy returns from rehab hell-bent on bloodshed and debauchery, Johnny finds himself in the middle of a vicious turf war with rival gangs for control of a city torn apart by violence and corruption. Can the brotherhood survive?

Notably, this DLC does take a hefty chunk of hard drive space: a total of 1.8GB.  At a price of 1600 points, or $20 USD, this is also quite a hefty chunk out of your wallet, but we expect it should be will worth it.  Also, this DLC does bring along another 5 achievements for the completionists out there.  So, if you want to get it, pick up some Microsoft Points (because you likely don’t have enough) and queue up your download.  You can expect it to take quite a while though, this is a relatively big file, and a lot of people will be downloading it.

We’ll be online tonight playing it, and you can hit us up on our Twitter if you want to discuss it more in depth with us.
