Xbox One players have some new backwards compatible games to get their hands on today according to Xbox Live's Major Nelson. Here's the word from the man himself via Twitter:

Civilization Revolution and Insanely Twisted Shadow Planet are the games, and each brings a distinct flavor to the table. Civilization Revolution was one of the first successful console strategy games that came out all the way back in 2008 while Insanely Twisted Shadow Planet was one of those most stylish 2D Platformers in the Xbox Live Arcade.
Civilization Revolution was also a Games With Gold giveaway all the way back in February of 2014, so if you were able to claim it back then, the game should appear in your Xbox One library right now.
Both games got scores of 8/10 in their official GameZone reviews, so for more on each game, you can check out the Civilization Revolution review here and the Insanely Twisted Shadow Planet review here.
