Plot Dump: The Campaign for Ada's campaign.Explanation Resulting from the majority of the game's plot details and backstories of the villains and other important information that is found through the Serpent Emblems on Ada's campaign.
Genius Bonus: During Chapter 3 of Chris' campaign, while tracking the Iluzja through the Poisawan district, one part of the area resembles an extremely unhygenic dentist's office, complete with a filthy glass case full of dentures. In real life, the Kowloon Walled City, which this part of the game was based on, was infamous for it's large number of unlicensed dentists, and a case full of dentures almost identical to the one seen in the game was featured in an old German documentary about the Walled City.
The same can be said the other campaigns, to a degree. The game recycles the angry, brooding, vengeance-driven Chris from Resident Evil 5 during the majority of his chapters. Jake and Sherry's campaign can be seen as a retake on Resident Evil 3 (Ustanak being the Nemesis counterpart). Ada's campaign is much like her Resident Evil 4 campaign, tailing the rest of the cast and filling in details as she goes along.
Urban Legend of Zelda: Rumors circulated of an Updated Re-release known as Resident Evil 6: Final Hope which would bring the game to Wii U as well as include an additional campaign for Claire Redfield.
