Provided that you have 7800 War Assets or more, Commander Shepard will survive the blast, along with the entire Normandy crew. Go up the path to the RIGHT to choose the Destroy ending, where you will be prompted to shoot a certain pillar. When Shepard finally gets to the Citadel after the Catalyst is docked, you will be presented with three major paths. But out of the four, you absolutely HAVE to choose to DESTROY if you want Commander Shepard to live, as per RepublicWorld. 'Mass Effect 3' has a total of four endings: Destroy, Synthesis, Control, and the so-called 'secret ending' called Refuse (a topic for another time).

In 'Mass Effect Legendary Edition,' all you have to do is collect as many war assets as you can, because the multiplayer requirement has finally been removed.

In the original, non-Legendary Edition version of ME3, the only way to get your TMS to 100% is by playing the multiplayer, because the default TMS always stands at 50%. To get the best ending, your TMS level must be at 100%. Unless, of course, you doДЄnother thing that's critically tied to your war assets is Total Military Strength (TMS), as stated by GamesRadar. It's also the main reason why it is extremely recommended that you play through all three games because starting off directly from ME3 will not get you enough assets to get a good ending. This includes armies, weapons, technologies, and allies.

War assets can be anything you gather or anyone you recruit throughout the main campaign, including the ones you get from playing through the first two games of the trilogy.
