It is no secret that Bioware is currently developing Mass Effect 4 and the game is going to be a fresh restart in the gaming series. Just recently, the game developer went public to unveil new concept arts while teasing a little about the game.
While not much is revealed, it is teased that the protagonist will start out as a nobody and dreams about being a hero. Obviously, the character is not going to achieve his dream in one title. As such, it is safe to assume that Mass Effect 4 will be a start of a new trilogy or even more.
It is also said that the cut-scenes will be toned down throughout the game. Bioware revealed that such implementation will make it more immersive for the players.
Like the first trilogy, Mass Effect 4’s protagonist will be aided by companions. So we are not looking at one hero but a team of heroes. Bioware described the companions as an absolute central piece of the game.
