OPENZ
An open world overrun by the infected, from the Church Lazarus camp to the sewers of City Center. Scavenge, drive, shoot, bleed, and come back the next day. Alone if you must, together if you can.

What's in the box
- One county: towns, farms, forest, an airport, sewers
- 1 350 vehicles parked where they died
- 64 modern firearms, with muzzle flash
- Hordes, weather, fog, snow, rain
- Voice chat, co-op, PvP, a GPS watch
Latest dispatch
- A whole island. 12 farms with quests, 13 villages, cabins under siege, a downed helicopter.
- Trees in the wind. They sway with the weather.
- Remade. Weapons, outfits, props, vehicles and zombies.
- Guns held right. Finger on the trigger, muzzle flash at the end of the barrel.
- Full-auto and melee strike. Rifles fire full-auto, and you can hit with the gun in your hands.
- Cars that drift. They follow bumps and slopes, and slide on the handbrake.
Watch






The County
VROOM
Drive anything
Cars, pickups, buses, army trucks, boats, a helicopter, a plane, and horses. Seats for your friends, fuel to find, doors that swing, bodywork that dents, engines that smoke and burn. Leave the wheel: your passengers stay in.
1 350 vehicles on the mapBLAM
Modern firearms
Pistols, rifles, snipers, shotguns with real spread, a bazooka. Aim down sights, automatic fire, ammo that runs out, impact marks on walls and cars. Fire from the passenger seat of a moving truck.
64 weaponsGRRAAH
They come in groups
The infected hunt in packs, hear your engine, follow your noise and surround you. Every wound bleeds and leaves a trail. Bandage, or die slowly.

Weather that matters
Fog rolls off the lakes and through the forest after the rain. Snow settles and melts. Puddles form. Night is dark. Your headlights are a beacon for everything out there.

Scavenge and settle

OpenZ is a free development build, for testing and feedback. It stays free until every licence is cleared. There is no paid version, no paid access, no paid content.
If you want to help cover what it costs to make (the server, the tools, the late nights), you can send a voluntary donation. It gives you nothing extra in the game, and it never will.
