20Shepard Andromeda Initiative Theory
One theory that many fans agree on is that Commander Shepard had to know about the Andromeda Initiative. The Initiative was initially founded in 2176. The events of Mass Effect 1 take place in 2183. During this year Shepard becomes a Spectre, which would have given him
high level clearance to classified information. This means that any documents on the Andromeda Initiative, which would have already been in full swing at this point, would have been available to Shepard.
Along with this, in the Mass Effect 2 DLC Lair of the Shadow Broker, Liara T’Soni becomes the new Shadow Broker and provides Shepard with permanent access to the base, along with its wide range of files and footage. It is hard to imagine that there would be no files on the Andromeda Initiative. Video logs in Mass Effect Andromeda further prove that Liara had contact with Pathfinder and main member of the Initiative, Alec Ryder, before the Initiative's departure.
