Surviving can be difficult, but keep some of the following tips in mind and your attempt should go more smoothly.

Aim for the head. All weapons do extra damage when you hit that area of a zombie's body.

Be careful to avoid dehydration, which fills gradually if you don't find water. If it fills, you could die even when you are otherwise healthy, so make sure you bring along bottled water or a refillable canteen.

Kill zombies whenever possible and be sure to use the experience points you gain to unlock passive enhancements, such as improved accuracy or stamina.
