Via Double Plus Undead comes this news story about an increasingly popular variant of the game of 'tag':
Welcome to the world of Humans vs. Zombies (HvZ), a tag-like game that is the latest trend in campus entertainment. An HvZ game typically involves hundreds of students and runs 24 hours a day for days on end; dwindling numbers of humans try to fend off and outlast growing legions of zombies.
The rules are fundamentally simple: Zombie tags human, human becomes a zombie. Unlike movie zombies, with shambling walks and undead makeup, zombies in the game just wear headbands to distinguish them from armband-wearing humans. And they are free to sprint.
Humans ward off zombies with Nerf guns or by hitting them with a balled-up sock — a defensive move that stuns the zombie, usually for 15 minutes. The goal is to still be a live human at the end.
