Four more Xbox 360 games are now playable on Xbox One.

Microsoft's Larry "Major Nelson" Hryb announced today's arrivals on Twitter, which include Call of Duty: World at War, E4: Every Extend Extra Extreme, Encleverment Experiment, and FunTown Mahjong.

World at War is not the first Xbox 360 Call of Duty title now playable on Xbox One, as it joins Call of Duty 2, Call of Duty 3, and Call of Duty: Black Ops.

Hyrb also confirmed today that all backwards-compatible Call of Duty titles can now be purchased directly from the Xbox One. Before this, some needed to be purchased through Xbox.com, apparently.

If you own any of the four games added to the backwards catalog today, they should show up automatically in your Xbox One game library. Alternatively, you can buy them from your Xbox One console or through the Xbox.com links below.

There are now more than 250 Xbox 360 games playable on Xbox One through backwards compatibility. You can see a list of all of them right here.
