To import your character into Mass Effect Legendary Edition, you must first create your character in Part 1. After that, you will need to complete the entire previous game.
This means that you will have to play through the game and complete the very last mission in the game. When you have done so, the game will then allow you to import this save into the next one after marking it as importable. When this happens, you will be able to import your character into the next game in the series.
Having said that, if you want to import a character from Mass Effect 1 to Mass Effect 2, all you need to do is click on Create New Game. This will then give you the option to choose a male or female character, but the option you want. to select is the one called Import ME1 character.
The option will be right under the male and female option, but if you don’t see the option, it probably means you didn’t do something right or didn’t complete the last mission in the game. You can also copy your characters from the original games to the legendary edition. However, this only applies to the second and third games, as the first one does not support the feature due to technical issues.
However, to import your saved data from the original second and third set, all you need to do is find the documents folder for Bioware. Next, locate the save file for your characters and then copy it to the equivalent of the legendary edition. After that, you can continue where you left off in the original games.
