General Kim Rok unleashed a virus which transforms humans into zombies. As one of the few survivors, the player has to protect the house from attacking zombies.

Each day is divided into day and night. During the waking hours, the player has 120 seconds time to build the defenses. Examples for things to buy are landmines, fences, wild plants (give buffs while standing on them), distractions, guns or ammo. When night approaches, zombies attack and need to be killed with the weapon of choice so they can't destroy the house. The player character is directly controlled and can aim the weapon in eight directions.

Each kill rewards money and, in case of the fat zombies, power-ups. Before starting a new game, the player can choose a character (differentiate in special attack and starting weapon) and the difficulty level (easy and normal goes over 40 days while hard mode is unlimited).
