Mass Effect 3 Guide: Act 1 Earth Walkthrough, Key Loot, and Early Decisions
This section of a Mass Effect 3 wiki guide focuses on the game’s opening stretch—what to pick up, where to go to find key items, how to get through the early combat without losing momentum, and which decisions matter for the direction of your run.
At the start of the story, Commander Shepard—freshly removed from duty due to their actions in Mass Effect 2—has to break free from Earth and move fast. The immediate goal is survival, but the bigger mission is stopping the Reapers from wiping out every sentient species across the galaxy. The catch is that every step forward carries a price, and one trip tied to Mars brings both something to hold onto and something painful to lose.
