Start the game with a wild cutscene. Once you open the door the game will load for a bit.
Right away the action begins as you are surronded by zombies. You have no weapons other then a flashlight. You must make it out alive.
You can push Zombies with the ZR button to make a way through. Head Straight ahead, then hook right into the room with the ladder. Go up the ladder and down into the ventilation shaft. You will fall.
Get up and look around turn your flashlight on. Take time to look at on screen prompts and figure out game control. There will be NO hints at all in the intro.
You must make your way down an escalator through a brown door. If you hear a zombie scream you are close. Yet you should start running to the door. Once through the door, the intro is over. ZOMBI U logo pops up and game begins.
