Zumbie is a game about surviving the zombie apocalypse with the help of your friend(s). One player plays as the shooter, who is a blind and limping but luckily has an endless supply of shotgun shells.
The shooter must hold the mobile device in the normal phone orientation (hotdog, not hamburger) and should not be able to see the screen, and must use a mobile device as a gun. Pick a name, and ask your friend(s) to play as a spotter. They must give you directions and help you survive as long as possible.
Your rotation will match the rotation of the shooter. Press the screen to shoot, and shake the phone vertically to reload.
