Reddit reviews Resident Evil: City of the Dead

They're actually going to re-release the books soon with new covers:
Underworld - City of the Dead - Nemesis - Umbrella Conspiracy - Caliban Cove

I remember arguing a couple of years ago that the Idea of the Ganados and the Majini was borrowed from Caliban Cove where they had zombies that were trained to be basic ground troops and could carry weapons and use them.
