The sci-fi role-playing epic continues, as the Mass Effect story delves into darker territory and the fate of Commander Shepard, his crew and the entire galaxy.

A streamlined combat system makes the game even more action-packed than before, with a new regenerating health system that means you spend less time fiddling with menus and more time shooting enemies. You can also direct teammates individually with a simple press of a button, giving you greater tactical control over every encounter.

The number of planets you can explore, and the complexity of the sub quests you find on them, has been greatly expanded from the first game - giving you a whole galaxy to explore at will. The original game was the most cohesive mix yet of action game and role-player and this sequel goes even further in combing both genres into one giant space opera.
