Despite teases and reveals, there has not been much information about the upcoming Mass Effect Andromeda. In fact, we only know that the main character will not be Shepherd, and that it will take place in the Andromeda Galaxy long after the events of Mass Effect 3.
However, a “leak” of sorts has hit the internet, and it claims to be from a person with an early build of Andromeda. In it, via the video below, the person reveals that gameplay will be similar to the original Mass Effect trilogy. However, there have been improvements, such as more abilities for the Omni-Tool. Also, traveling to other planets has been updated, and will be manually done now. Finally, a new ship is apparently coming into play, one that is very different from the Normandy.
You can check out the full leak video below. However, do not that this has not been confirmed by Bioware.
