Best to tick off everything, just to be sure.Įither way, you may want to start planning ahead as soon as you start the first game, to ensure all your favourite heroes survive the battles to come. Mass Effect Legendary Edition removes multiplayer, however, but essentially you’ll just need to complete nearly all of your available objectives to get a high enough number for the best ending. The original Mass Effect 3 ending is determined by a combination of choices (War Assets) and participation in the game’s multiplayer mode, Galaxy at War. This determines which conclusion you get and even if Shepard survives. The first two games have fewer endings, but the Mass Effect 3 ending factors in decisions made throughout the trilogy into your final ‘Effective Military Strength’ rating. BioWare complicated things with Mass Effect 3.
