For now anyway... There's a red pulsing in the distance... OH NO! IT'S A ZOMBIE! You're losing health, but what's this? A white pulsing from around a corner, a healer! You'll stay human for a little longer... Hopefully long enough to check out this guide! Using Circuit Playground Express you can make a game that's half laser-tag half hide-and-seek.  This game requires at least three players, which means it requires at least three Circuit Playground Expresses. You can play with as many more than three, as many as you want! **It's great for workshops, classrooms, camps or other groups of 3 or more!** The more people you have, the more fun the game gets. This guide will go through the code for the game, explain how it works and how to play.
