HVZ

HVZ stands for Humans vs Zombies, a live-action game in which players assume roles of humans or zombies. Origin on college campuses in North America in the early 2000s, it has since spread to universities, high schools, and broader communities. The game combines elements of scavenger hunts, role-playing, and tag, and is often run over a day or more.

Gameplay centers on two factions. Humans attempt to complete missions, collect supplies, and reach safety zones, while zombies strive to convert humans by tagging them. Infected players become zombies and join the pursuit. Some rule sets include limited resurrection or cure mechanics; missions and objectives guide progress, and roles can rotate or evolve as the game advances.

Equipment and rules commonly emphasize safety. Most games use non-harmful props such as foam swords or Nerf blasters, with strict safety guidelines and prohibitions on real weapons or dangerous contact. Safe zones exist where humans are immune. Campus policies frequently constrain hours and boundaries, and organizers typically require waivers, health statements, and monitoring by staff or trained volunteers.

Organization and culture: HVZ is usually run by student clubs or campus activity groups, supported by volunteer coordinators, referees, and security liaisons. The format varies widely by campus, including infection rates, mission structures, and duration. The activity emphasizes teamwork, strategic planning, and community involvement, and often fosters social bonding among participants.

Variants and reception: Some versions emphasize strategy and stealth; others focus on cooperative storytelling. HVZ has inspired regional and online communities, tutorials, and shared rule sets. While popular, it raises safety, inclusivity, and consent considerations that organizers address through clear rules, opt-in participation, and accessibility options.
