Mass Effect - Xbox Mooch

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!

Features: Incredible science-fiction RPG with a rich, engaging story line - 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 fiber 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.

Exploring uncharted worlds and uncovering a mystery that defies imagination - 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.
