Roughly four months after it came packaged with the PS3 version of Mass Effect 2, the motion comic Mass Effect: Genesis is coming to the Xbox 360. Serving as both a story primer and a means to create a save from the first Mass Effect without playing the full game, the download is 227.79 MB and will cost $5.

“This digital comic back-story was created by BioWare and Dark Horse comics, reads the description. The 15 minute interactive experience allows you to make the key choices of Mass Effect 1. This retelling will also let you have those choices reflected during Mass Effect 2.”
