Mass Effect 3 War Assets Locations and Readiness Guide
Mass Effect 3 endings are subjected to how much prepared you are for your final battle against the Reapers.
Your single-player and multiplayer efforts contribute to your final readiness score that is the single most important factor if you want to experience a perfect ending or a good ending at least.
You are roaming the galaxy for a single purpose, and that is to collect as much help as possible and save Earth. If you fail, there won’t be any Earth left to come back.
