The document describes aspects of zombie-themed video games that will be referenced in the development of the author's own zombie game. Key aspects that will be included are: zombies that run and emerge from graves in a dark, churchyard setting; multiple levels that increase in difficulty; different guns that can be purchased as the player progresses; and visual indicators of the player's remaining ammunition, health, and money for upgrades. Research was conducted on popular zombie games to identify common features such as dark atmospheres, single-player modes, and representations of ammunition counts.
