The Xbox One just added another title to the list of backwards compatible games that can be played on the console. The beautiful and trippy twin-stick shooter Geometry Wars: Retro Evolved can be downloaded by anybody who already bought the game on Xbox Live.
Originally intended to be a mini-game for Project Gotham Racing 2, Geometry Wars was so much fun that the developer chose to continue development and make it into a full game. Geometry Wars enjoyed its tenth anniversary a few months ago and the lead developer found the game to still be amazing.
