Mass Effect is a science-fiction action and role-playing game (RPG) created by BioWare, the commercially and critically acclaimed RPG developer of Jade Empire and Star Wars: Knights of the Old Republic. Mass Effect delivers an immersive, story-driven gameplay experience with stunning visual fidelity. As the first humans on the galactic stage, players must uncover the greatest threat to civilization. Their job is complicated by the fact that no one will believe the truth, but the world must be convinced of the grave threat at hand.
Players will travel across an expansive universe to piece the mystery together. As they discover and explore the uncharted edges of the galaxy, they come closer to an overwhelming truth learning that the placid and serene universe they know is about to come to a violent end and that they may be the only people who can stop it.
On a distant planet an amazing discovery is made. Players must determine the fate of humanity as they lead an elite tactical strike force in an effort to stop an entity so malevolent that it threatens to tear apart the very fibre of galactic civilization. Mass Effect will take players to new depths for an action-RPG, where, unlike in most RPGs, they will be faced with morally complex decisions that have significant impact on the fate of all life in the galaxy. Players must succeed in their quest no matter what the cost.
