About this game

Description

Supplied by the Steam store

PROTOCOL Z is a zombie sandbox. Watch a living town go about its day, then unleash the outbreak, take control of anyone, call down disasters and see if the town holds the line.

A town that lives without you. New Hudson runs on its own. Families wake up, drive to work and walk their kids to school. After school the kids head for the playground, the slide and the jungle gym, or toss a frisbee in the park. Shifts change at the hospital, the police station and the military base. The hotel's football team plays its morning game, and inmates pump iron and shoot hoops in the prison yard.

Then you let the dead in. Drop zombies anywhere, dig tunnels for them to crawl out of, or start with one bite and watch it spread. The infected chase the sound of gunfire, smash through fences, doors and walls, climb onto cars and drag people from their beds. Anyone they kill gets back up as one of them.

Special infected. Some are worse than others: leapers that pin you down, lashers that drag you off the street with a whipping tongue, spewers of burning acid, bloated ones that burst, and hulking brutes that shrug off bullets.

Become anyone. Take control of any townsperson, or any zombie, and play in first person. Fight with your fists, pistols, rifles, shotguns, rocket launchers, flamethrowers and C4. Jump, swim out into the sea, and dive below the surface. Commandeer a car and send bodies flying. Break the law and the police will hunt you down.

The town fights back. Police respond to calls. Ambulances collect the wounded. Families board up their windows. When the outbreak gets bad, the military declares martial law: soldiers build barricaded checkpoints with floodlights and watchtowers, enforce a curfew, patrol the streets, and blow up the zombies' tunnels with C4. Every barricade can be shot, rammed or blown apart.

Build your own disaster. Place humans, zombies, vehicles and whole buildings anywhere on the map. Then play god with tsunamis, tornadoes, floods, hurricanes, sinkholes, meteors, blizzards, dust storms and landslides.
