A trio of artworks for the new Mass Effect make you guess the first information about the game
One image shows a galactic portal probably under construction, with mr 7 written on the side of the structure. "MR" could stand for Mass Relay, whilethe number 7 probably indicates that several are under construction; so the galactic portal could mean new Andromeda settings to explore.
The other image shows several structures that look rather massive and resemble remnant architecture in Mass Effect Andromeda; remnants are a mysterious and advanced civilization that once ruled the Andromeda Galaxy and disappeared before the events of the previous game. Finally, we see a spaceship similar to the landing shuttles used by the colonizers of the human race of the andromeda galaxy.
All this makes you guess that the next chapter of the series could always be set on Andromeda; The finale of Mass Effect Andromeda remained quite open, so the conclusions might be valid.
Waiting for details directly from Bioware, we leave you to the artwork.
