Description
Dropping a single infected walker onto a quiet morning street in New Hudson turns an ordinary workday into a full town meltdown within minutes. Protocol Z is a zombie sandbox simulator developed by CASH and Aria and published by GorillaGamesStudio. Set across a living town where residents drive to work, kids walk to school, and hospital shifts rotate on schedule, the experience lets you trigger an outbreak and watch police, ambulances, and military units fight to hold the line across solo, online co-op, and LAN modes. Right here on this catalog page you can check the Windows system requirements to verify your PC meets the 8 GB RAM and 4 GB storage minimums and look through screenshots and gameplay videos before unleashing the horde.
Beyond placing zombies, tunnels, vehicles, and entire buildings anywhere on the map, you can jump into the body of any townsperson or special infected in first person. Fight back with fists, rifles, flamethrowers, and C4, commandeer cars, or call down nine natural disasters including tsunamis, tornadoes, meteors, and floods while destructible walls and barricades collapse around you. Since the project is actively growing in Early Access you can visit this hub anytime to check the latest game version and read the current patch notes detailing recent performance optimizations and horde balance updates.
