“Call of Duty: Black Ops” Now Available On Xbox One
With "BOII" Presumably to Follow
Major Nelson announced that "Call of Duty: Black Ops" is available on Xbox One via backward compatibility.
Microsoft previously announced that "Black Ops" would be coming to the Xbox One a few months back. With the first and third now on Xbox One, this leaves "Black Ops II" the only one out of the "Black Ops" series, though it may be come later down the line. Other games, such as the "Bioshock" series and "Red Dead Redemption" are expected to be available in the near future.
