The game takes place in the 23rd century, when humankind has just started to explore space with manned craft an endeavor that soon takes our race beyond the familiar confines of our solar system and into the heart of the galaxy.
What we encounter is a war between artificial and organic life that has dangerous and far-reaching consequences. To protect the peace, your character becomes the first human to be indoctrinated into an elite military force called Spectres. You will control a spaceship and crew to enforce your mandate, with your first mission being to subdue a rogue agent.
Of course, this job is just the beginning of a larger adventure, and BioWare even plans to make Mass Effect a trilogy something BioWare joint CEO and co-executive producer Ray Muzyka says is easily done.
Were investing in a whole suite of development tools and planning a story arc spanning games and expansions in the future that will allow us to quickly and efficiently create content for future games, Muzyka said. We are quite confident that BioWare will be able to successfully create and deliver the entire experience to the players, and our goals is to do so during the life span of the Xbox 360.
