Locate and read the "Day of the Kungfu Zombies" books in various levels. Note: When you look at this book, it will not highlight an action response. You have to search for the book then press ACTION to read it. Your character will say "I know Kung Fu?", then tattoo will appear on your hands. Your hands are now stronger, and can kill zombies.
At the start of the game, Jack notices a stranger standing in his yard.. The game will instruct you to go out and confront him. Instead, go upstairs to the attic and find your .22 rifle. The zombie will start bashing his way into your house, but it is better than running up to him unarmed, as he will almost always bite you. Also, the key to the shed in your backyard is in the basement. If you go downstairs before coming into contact with the zombies, you can get a revolver, ammo, and a hammer from the shed. These make it much easier to fight off the walking dead at your house, and you can complete the level twice as fast.
