Attack on Titan, colossal edition. 3

After barely beating back a Titan incursion at Wall Rose, the Survey Corps is left facing ever more mysterious questions. Yet there is no time to answer them, as humanity's mortal enemies, the Colossus Titan and the Armored Titan, suddenly and dramatically appear. Shocked at the identities of these genocidal agents, the Corps can't respond quickly enough. What seemed like one more victory on a march back to Wall Maria has now become a mad scramble to win back hope for humanity at any cost.
