Section 1 - Game Overview

Game Concept

  • The U.S. government has quarantined the entire West Coast in an effort to contain the zombie plague manufactured by mad scientist Dr. Grudge. The player assumes the role of Dr. Grudge, leading a horde of zombies on a march across America, culminating in the destruction of Washington DC.

Gameplay

  • Levels end at some key destination or completion of objective (destroy building, etc). The player must evade his zombie herd while guiding them through obstacles. There will be enemies like gunmen and bears which can be turned into zombies. At the beginning of every level, after a brief description of the level, the player can choose specific zombies from his herd to use in the level. The game will involve solving puzzles like those in Lemmings, but action/combat will be emphasized as well.
