There's new (old) games becoming backwards compatible on Xbox One all the time, but the latest additions are noteworthy. Doom 3 is worth a mention because it lands ahead of the rebooted Doom, while Monaco: What's Yours is Mine is a brilliant fusion of Pac-Man and Hitman. Other games added this month include Sonic the Fighters, Gunstar Heroes, and Duke Nukem Manhattan Project. To see the entire list of backward compatible games hit this link.
