Creative director of the game, Mac Walters, explained in the video above that the male and female versions of the main character will appear in the game at the same time. The main character will have the last name Ryder and similar to Shepard in previous titles you can customize a male or female character to your liking. The other will then become your brother or sister.
“What a lot of people don’t know, little surprise here, is that these two are brother and sister,” Walters said (via Polygon). “And they both exist in the game world at the same time. So if you’re playing as the sister Ryder, female Ryder, your brother is somewhere in the universe.”
He then explained that instead of focusing on one central hero, the game will focus on both of them as a team. Also mentioned is the fact that we have already seen more of their family, with their father appearing in the E3 trailer that featured the sister character.
We can expect to hear more names and details about the family affair as Mass Effect nears release. EA has noted that we will get more reveals and trailers after Battlefield 1 and Titanfall 2 release later this year.
Mass Effect: Andromeda is set for next year, 2017.
