Besides that i think events might be paralel sth that happened in
"Source code" 2011 movie.
Its criminal/doomsday event movie that sets action on a train before it gets blown up in terrorist attack. Protagonist searches entire train for terrorist.
Calypso protocol could be triggered on some doomsday event. Something Albrecht did not forsee in his plan. Whatever it was.
My guess is that paranoid Albrecht afraid of man in the wall recreated matrix out of memories of protoexcal. He tried to cut himself or rather cut off the man in the wall from rest of the world. He failed. The man in the wall has taken over the matrix. Your trapped there with him just like in "the evil within" game. And ur ideal plan is to make it out alive from this matrix. By Fleeing you will free man in the wall to origin system.
Theres no ending just more crossroads. And 10 more years of warframe.
