Microsoft has added another game to Xbox One's steadily growing backwards compatible library. Only one new Xbox 360 title is playable on the current-gen console this week, but it's one of the system's most popular: Call of Duty: Modern Warfare 2.

Originally released in 2009, Modern Warfare 2 was one of the most acclaimed entries of its generation and was one of the instalments responsible for propelling the Call of Duty series to its current popularity. GameSpot awarded the Xbox 360 version a 9/10 in our Modern Warfare 2 review and called it "a thoroughly excellent package that is sure to thrill shooter fans and deprive them of sleep for months to come."

If you still have an Xbox 360 copy of Modern Warfare 2, you can pop the disc into your Xbox One to initiate a download and begin playing. If you've previously purchased the game digitally, it'll automatically appear in the Ready to Download section of the My Games and Apps menu. Modern Warfare 2 is also available to download from the Microsoft Store, and it's on sale for $15 as part of this week's Xbox One Deals with Gold.

Microsoft has been rolling out new backwards compatible games for Xbox One on a near weekly basis recently. Earlier this month, two Xbox 360 Tomb Raider games, Tomb Raider Legend and Tomb Raider Anniversary, were added to the backwards compatible library, while a pair of Splinter Cell games arrived at the start of this month.

More than 400 Xbox 360 games and 30 original Xbox titles are now playable on Xbox One. You can see them all in our full list of backwards compatible games.
