It's quite annoying how we have pretty much solid placements for every canonical entry into the series aside from Vendetta. The novel explains the Lanshiang incident was 'not too long ago' and the New York outbreak is described as 'late winter'. Based on this, I have the prologue in Mexico as Autumn 2013 and the New York attack circa February 2014. Once Chris finishes his dealings with Arias he leaves Silver Dagger and returns to Alpha Team, leading into Heavenly Island.
This is what I would like to know for marathons. Does RE7 Daughters take place before Vendetta?
