Another Xbox 360 game is now already playable on the Xbox One. Major Nelson said in a tweet earlier that the game is now available on the Xbox One.

This exclusive arcade live game features the original Retro version and the once new Evolved mode. Geometry Wars if you don’t know is a 2d-shooter, which has you face off against hundreds of enemies. The goal: survive as long as you can.
The game is priced at $4.99.
