There is still a lot of details that we do not know about the upcoming Mass Effect Andromeda game and one of them is the alien races that we will be seeing in the new game.
According to Mac Walters, the Creative Director of the game, a few of the aliens might not make it into the first game which means that there is going to be more aliens added after this game but not all of them will be making an appearance in the first game.
We know that races like the Asari, Turians, Salarians, Humans and Krogans will all make it into the first game but alien races like the Batarians, Volus,Elcor, Drell, Geth, and Hanar might not make it as well.
Fans were hoping that the Quarians will make it into the new game but we have not seen them in any of the trailers, poster, and screenshot of the game. The new Mass Effect Andromeda will be released in March 2017.
