This section of IGN's Mass Effect wiki guide is the main walkthrough, guiding you through every level, combat encounter and major story decision in the game. We'll guide you through the entire game, from the first conversation aboard the Normandy right up to the final boss of the game.

The beginning of the game starts you off on the SSV Normandy SR-1 prototype under the command of Captain Anderson. A routine shakedown run at the human colony of Eden Prime turns into something far greater, as a terrifying force makes a play for a discovery of galactic importance.
