Fans have been clamoring for bigger-name Xbox 360 games to go backward compatible on Xbox One, and now Microsoft is at long last delivering. Last week came Call of Duty 3 and now, as revealed by Xbox's Major Nelson, comes Call of Duty: World at War along with three other games.

Call of Duty: World at War was the last entry in the franchise set in World War II, with players playing as both American and Russian forces toward the end of the conflict. Both Call of Duty: World at War and Call of Duty 3 were developed by Treyarch, which would go on to create the Call of Duty: Black Ops series, the first of which is also backward compatible. The Infinity Ward-developed Call of Duty 2 was also recently made backward compatible.

That means almost half of all available Call of Duty games for the Xbox 360, aside from the Modern Warfare trilogy, Call of Duty: Black Ops II, Call of Duty: Ghosts (which also released on Xbox One), Call of Duty: Advanced Warfare (which also released on Xbox One) and the digital-only Call of Duty Classic, are now backward compatible for Microsoft's current console. Major Nelson revealed that players can now also purchase all of the backward compatible Call of Duty games directly through the Xbox One, rather than having to use an Xbox 360 or Xbox.com as was the case previously.

It is, however, unlikely that fans will see more popular titles like Call of Duty 4: Modern Warfare or Call of Duty: Black Ops II go backward compatible. Activision is releasing an HD remaster of Call of Duty 4: Modern Warfare for Xbox One this year alongside Call of Duty: Infinite Warfare, and it seems likely the publisher may have plans to do something similar with the incredibly popular Black Ops II.

As for the other three games becoming backward compatible alongside Call of Duty: World at War, they aren't much to get excited about. Xbox 360 arcade titles FunTown Mahjong, E4: Every Extend Extra Extreme and Encleverment Experiment join the list of playable Xbox 360 games on Xbox One. Those who own them already should find them added to your "Ready to Install" game list. The addition of the games brings the grand total of backward compatible games to more than 250.

There are still a number of games that are confirmed to be going backward compatible but haven't yet, including the JRPGs Blue Dragon and Lost Odyssey. BioShock, BioShock 2 and BioShock: Infinite are also set to become backward compatible, despite the recent release of BioShock: The Collection on Xbox One.
