BioWare has officially commented on the new Mass Effect: Andromeda books that emerged online recently. In a post on its website titled “Expanding the Mass Effect Universe,” the developer explained the books will give the studio “the opportunity to expand the Mass Effect universe and bring new stories to life outside of the games.”

The new novels will be published by Titan Books, BioWare confirmed. As for who is writing them, what stories they will tell, and when they’ll arrive, those details are being saved for a later date.

“Unfortunately, it’s still too early to go into more detail about the books or when they will be released,” BioWare said. “We are still in the midst of the creative process, but we are working with a talented group of writers to bring these exciting new stories to our fans.”

According to the report, there will be four new Mass Effect novels in all. The first one, which is reportedly titled Mass Effect Andromeda: Initation, is being written by N. K. Jemisin; the report said it’s due out in August 2016. The document also revealed that Mass Effect series writer Mac Walters will pen the last one, which does not yet have a title but is slated for March 2018.

There is no word yet on who will write the second and third books, but release dates of March 2017 and September 2017 were listed for them.

Andromeda the game was originally scheduled to come out in 2016, but in May, BioWare announced that the game is now coming in “early 2017.” The game was delayed “to make sure we deliver everything the game can be and should be,” BioWare said at the time.
