BioWare’s Project Director Michael Gamble has officially confirmed on his Twitter that Mary DeMarle will be in charge of the script for the upcoming Mass Effect game :
I am really excited to announce that Mary DeMarle will be joining the Mass Effect team as Senior Narrative Director. You’ve seen her work in Guardians of the Galaxy and Deus Ex. She is amazing.

For now, the only thing known about the new Mass Effect is that it exists and is being worked on, which BioWare said in 2020, when they released the first teaser of this production. There are no confirmed facts about the plot, although you can guess a lot from the clip itself, because the creators left a lot of clues in it.
In Mass Effect Legendary Edition, the new edition of the original trilogy, and in Mass Effect: Andromeda , you can play it on PC and the latest consoles.
