Mass Effect is a science-fiction action and role-playing game created by BioWare, the commercially and critically acclaimed RPG developer, due to be released on the 23rd of November 2007.

Mass Effect delivers an immersive, story-driven gameplay experience with stunning visual effects. 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.

In addition to the main story arc of the game, players will be able to visit a large number of uncharted, unexplored planets that are side quests independent from the main story. At any time during the campaign, a player can choose to explore one of these planets and have an opportunity to discover new alien life, resources, ruined civilizations and powerful technologies.

Mass Effect takes full advantage of the hardware of Xbox 360, providing players with exciting new experiences, including photo-realistic, high-definition graphics on an epic scale, and amazingly realistic characters who bring the world alive. Players will be immersed in a massive universe of unbelievable scale, meet characters that feel real and, most important, interact with them in ways that have never been possible before. As the future of gaming goes online, premium downloadable content and recognition of achievements will be available via the Xbox Live online game service.
