Shack PSA: Modern Warfare 2 on Amazon Includes $20 Game Credit

Amazon is offering a $20 voucher for future video games purchases from the retailer with copies of Call of Duty: Modern Warfare 2 on PC, Xbox 360 and PlayStation 3.

The offer includes both the $60 regular edition and $80 'Hardened' edition--packing an art book and code for the upcoming downloadable release of the original Call of Duty.

While this offer sadly does not cover the $150 night vision goggle and plastic head-toting Prestige Edition, a $10 voucher is included with the Xbox 360 version only.

Infinity Ward's shooter sequel arrives November 10, with the PC version controversially not supporting dedicated servers. Thanks to Shacker kungfusquirrel for the tip.
