If you're a big fan of the Geometry Wars series of games, you'll be happy to know that Geometry Wars Retro Evolved for the Xbox 360 is once again available as a backward compatible game for the Xbox One.
Geometry Wars Retro Evolved was included in the original lineup of backward compatible games when the feature launched for the Xbox One late last year. However, Xbox's Larry "Major Nelson" Hryb confirmed via Twitter that it is now playable, indicating that it must have been quietly pulled from the list at some point.
In any case, if you hadn't yet tried the fast-paced geometric arcade shooter, you can snag it on the Xbox Store at the link below.
