Having defeated the invading Reapers Commander Shepard learns that an even greater threat has emerged. In the far reaches of space something has started abducting entire human colonies and Shepard has little choice but to work with the questionable Cerberus organisation to stop the most terrifying threat mankind has ever faced.
Despite its flaws the first Mass Effect took the action role player to a new level and this sequel improves upon it in nearly every way. In order to succeed the player must convince the best from around the galaxy to join their cause. The stories of these characters and your interactions with them are the driving force behind the majority of the game and this is all helped along by the improved conversation wheel that makes talking to your crew fluid and engaging.
The third person combat is also largely improved and now plays very much like a simplified version of Gears of War, the art of using cover now vitally important. Of course the character traits, such as cloaking and levitation powers are still present. Those that played the original will also be pleased to know that the slow loading times and long elevator rides have been almost completely removed.
The only criticism of this sequel would be the addition of resource gathering. This involves a dull planet scanning mini-game to collect minerals that can be used upgrade or build new armour and weapons and seems completely unnecessary. This is however a minor blip in a game that sets a new standard of what can be achieved in the role playing genre.
