Similar to Modern Warfare 2, Call of Duty: Black Ops will be getting two special editions of the game in addition to the standard retail version. Details about the two edition, Hardened and Prestige, have not been revealed but will retail for $79.99 and $149.99 respectively in the US.
If Modern Warfare 2’s special editions are anything to go buy, you can expect free DLC content in the Hardened edition along with a special game case. The Prestige edition will likely include something similar to the Nightvision Goggles.
