Play the role of either a zombie or a human in the dark streets of a deadly city. Your mission is to survive for as long as you can and convert zombies into humans and humans into zombies. If you change into the other form for more than 5 times, you will die and the game will be over. Collect power ups and use them for your advantage. Beware of the white zombie dog and the drain covers that might bring death to you instantly. Use the WASD keys to move around and the mouse to aim and fire or jump towards the enemy to convert it into the other form.
