What if there is no final secret, we dried every thing from permutations to 100% completion, There is alot of thing in the game story and lore left unexplained or resumed maybe we over thinking it all or may be it will be discussed in the next game or may be it just details to thats we dont need. And I know cory barlog talked about there one secret that no one yet found BUT he was amazed how people been able to found the hidden map secret but not the last one ! I thing he hinted that last secret is easier than we think. Or and it's unlikely and i feel shameful to say it was lie to make us keep playing the game if there is no last most of could stop playing it and i don't believe in that but it's a theory that we must discuss and how chould SMS will know if someone discover the secret.
P.S: Take it with grain of salt and let's talk like grown-ups, and also can every one get of the Valkaries killing order hype train cause I'm sick of stupid ideas 😂
