Infection / Zombies Format

Infection or Zombies formats revolve around a transformation mechanic that alters team sizes during the course of the round. The game typically begins with a small number of infected players often one or two who attempt to eliminate survivors. When a survivor is eliminated, they switch sides and join the infected, reinforcing the growing group of opponents.

This mechanic introduces a unique pacing structure. The survivors’ initial numerical advantage gradually erodes as infected numbers increase, creating a rising tension dynamic that rewards mobility, awareness, and adaptive positioning. Meanwhile, the infected team gains momentum as more players convert.

Rules vary between fields and events. Some versions require survivors to be hit a single time to convert; others may require physical tagging or a specific form of elimination. Certain variants incorporate respawn mechanics that allow infected players to re enter the game repeatedly, while survivors may be limited to single life participation.

This format thrives in large group recreational sessions, scenario events, and themed night games. Woodsball environments with natural terrain offer particularly strong settings due to the variety of hiding spots, choke points, and extended approach routes. Urban style constructed fields may include buildings, corridors, or kill house elements that favor ambush based play.

Narrative elements frequently appear in Infection/Zombies formats. Organizers may use props such as antidotes, supply crates, evacuation zones, or timed helicopter extractions as additional mission elements. In some events, survivors must reach a designated extraction point before the infected overwhelm them.

The format’s inherent asymmetry and escalating tension make it a popular recreational option, especially for large, mixed experience groups. Its simple ruleset and thematic potential provide accessible, high energy gameplay suited to varied player counts.
