Because when the real thing comes to pass, you need to be prepared.

Wow. I definitely missed out when I was at university. Where was the zombie vs. human war when I was taking classes?

This is a prime example of the most awesome things about campus life. Not even in (most) high schools would you get this kind of human vs. zombie action going on. (Nor would you be allowed to carry around Nerf guns in school.)

I love how complex the rules are. Very particular about what can be done, what happens, etc. Just the amount of strategy makes me want to play.
