Starting today Tuesday, December 23, you can download the Xbox Original, Halo: Combat Evolved, at a discounted price of 600 Microsoft Points (marked down from 1200 MSP). This deal is part of the Xbox LIVE Marketplace Holiday Deal of the Week. If you have not already bought this, there’s never been a better time. Even if you have the original disc, it doesn't hurt to have an extra copy on your 360's hard drive. You know. Just to be safe.
